收集整理的這篇文章主要介紹了
mybatis、ibatis 和spring集成
小編覺得挺不錯(cuò)的,現(xiàn)在分享給大家,幫大家做個(gè)參考.
mybatis是ibatis的升級(jí)版，spring也有自帶mybatis的orm。所以，搭建ibatis的框架也會(huì)有多種方式（我這里mybatis是3.0的，ibatis是2.3的，spring是3.0的，數(shù)據(jù)庫(kù)是mysql）。下面介紹3中方式
1，只是用mybatis3。
2，使用mybatis3+spring3(使用mybatis的SqlSessionFactory )。
3，使用ibatis2.3+spring(使用spring自帶的ibatis)
spring的orm包中只有ibatis，沒有mybatis。而mybatis和ibatis還是有些區(qū)別的，比如配置文件屬性不同。
?
第一種方式(只使用mybatis)：
1）jar包：
cglib-2.2.jar
asm-3.1.jar
mysql-connector-java-3.1.13.jar
mybatis-3.0.5.jar
junit.jar
2）mybatis配置文件：
[html] view plaincopy
<?xml?version="1.0"?encoding="UTF-8"??><!DOCTYPE?configuration?PUBLIC?"-//mybatis.org//DTD?Config?3.0//EN"?"http://mybatis.org/dtd/mybatis-3-config.dtd">??<configuration>????????????<settings>????????????????????<setting?name="cacheEnabled"?value="true"/>????????????????????<setting?name="lazyLoadingEnabled"?value="true"/>????????????????????<setting?name="aggressiveLazyLoading"?value="true"/>????????????????????<setting?name="multipleResultSetsEnabled"?value="true"/>????????????????????<setting?name="useColumnLabel"?value="true"/>????????????????????<setting?name="useGeneratedKeys"?value="true"/>????????????????????<setting?name="autoMappingBehavior"?value="PARTIAL"/>????????????????????<setting?name="defaultExecutorType"?value="SIMPLE"/>????????????????????<setting?name="defaultStatementTimeout"?value="25000"/>??????</settings>??????????????????<typeAliases>??????????<typeAlias?alias="pageAccessURL"??type="com.lgm.mybatis.model.PageAccessURL"?/>??????</typeAliases>????????????<environments?default="development">????????????????????<environment?id="development1">??????????????<!--????????????????????事務(wù)配置?type=?JDBC、MANAGED??????????????????1.JDBC:這個(gè)配置直接簡(jiǎn)單使用了JDBC的提交和回滾設(shè)置。它依賴于從數(shù)據(jù)源得到的連接來管理事務(wù)范圍。??????????????????2.MANAGED:這個(gè)配置幾乎沒做什么。它從來不提交或回滾一個(gè)連接。而它會(huì)讓容器來管理事務(wù)的整個(gè)生命周期（比如Spring或JEE應(yīng)用服務(wù)器的上下文）。??????????????????默認(rèn)情況下它會(huì)關(guān)閉連接。然而一些容器并不希望這樣，因此如果你需要從連接中停止它，將closeConnection屬性設(shè)置為false????????????????????????????-->??????????????<transactionManager?type="JDBC"/>??????????????<!--???????????????<transactionManager?type="MANAGED">??????????????????<property?name="closeConnection"?value="false"/>??????????????</transactionManager>???????????????-->???????????????<!--????????????????????數(shù)據(jù)源類型：type?=?UNPOOLED、POOLED、JNDI??????????????????1.UNPOOLED：這個(gè)數(shù)據(jù)源的實(shí)現(xiàn)是每次被請(qǐng)求時(shí)簡(jiǎn)單打開和關(guān)閉連接。它有一點(diǎn)慢，這是對(duì)簡(jiǎn)單應(yīng)用程序的一個(gè)很好的選擇，因?yàn)樗恍枰皶r(shí)的可用連接。??????????????????不同的數(shù)據(jù)庫(kù)對(duì)這個(gè)的表現(xiàn)也是不一樣的，所以對(duì)某些數(shù)據(jù)庫(kù)來說配置數(shù)據(jù)源并不重要，這個(gè)配置也是閑置的??????????????????2.POOLED：這是JDBC連接對(duì)象的數(shù)據(jù)源連接池的實(shí)現(xiàn)，用來避免創(chuàng)建新的連接實(shí)例時(shí)必要的初始連接和認(rèn)證時(shí)間。??????????????????這是一種當(dāng)前Web應(yīng)用程序用來快速響應(yīng)請(qǐng)求很流行的方法。??????????????????3.JNDI：這個(gè)數(shù)據(jù)源的實(shí)現(xiàn)是為了使用如Spring或應(yīng)用服務(wù)器這類的容器，容器可以集中或在外部配置數(shù)據(jù)源，然后放置一個(gè)JNDI上下文的引用???????????????-->??????????????<dataSource?type="UNPOOLED">??????????????????<property?name="driver"?value="com.mysql.jdbc.Driver"/>??????????????????<property?name="url"?value="jdbc:mysql://localhost:3306/appdb"/>??????????????????<property?name="username"?value="root"/>??????????????????<property?name="password"?value="123456"/>??????????????????<!--????????????????????默認(rèn)連接事務(wù)隔離級(jí)別??????????????????<property?name="defaultTransactionIsolationLevel"?value=""?/>??????????????????-->??????????????</dataSource>????????????????????????</environment>??????????????????????????????<environment?id="development2">??????????????<transactionManager?type="JDBC"/>??????????????<dataSource?type="POOLED">??????????????????<property?name="driver"?value="com.mysql.jdbc.Driver"/>??????????????????<property?name="url"?value="jdbc:mysql://localhost:3306/appdb"/>??????????????????<property?name="username"?value="root"/>??????????????????<property?name="password"?value="123456"/>????????????????????????????????????<property?name="poolMaximumActiveConnections"?value="10"/>????????????????????????????????????<property?name="poolMaximumIdleConnections"?value="5"/>????????????????????????????????????<property?name="poolMaximumCheckoutTime"?value="20000"/>????????????????????????????????????<property?name="poolTimeToWait"?value="20000"/>????????????????????????????????????<property?name="poolPingQuery"?value="NO?PING?QUERY?SET"/>????????????????????????????????????<property?name="poolPingEnabled"?value="false"/>????????????????????????????????????<property?name="poolPingConnectionsNotUsedFor"?value="0"/>??????????????</dataSource>??????????</environment>??????????????????????????????<environment?id="development3">??????????????<transactionManager?type="JDBC"/>??????????????<dataSource?type="JNDI">??????????????????<property?name="data_source"?value="java:comp/env/jndi/mybatis"/>??????????????????<property?name="env.encoding"?value="UTF8"/>??????????????????<!--???????????????????<property?name="initial_context"?value=""/>??????????????????<property?name="env.encoding"?value="UTF8"/>???????????????????-->??????????????</dataSource>??????????</environment>????????????????????????</environments>??????????????<mappers>??????????<mapper?resource="com/lgm/mybatis/config/pageAccessURL.xml"/>??????</mappers>????</configuration>?? ?
其中<environments>屬性是數(shù)據(jù)源環(huán)境配置，可以配置多個(gè)數(shù)據(jù)源配置。每個(gè)<environment>屬性代表一種配置方式。
加載事務(wù)配置<transactionManager > 和數(shù)據(jù)源配置<dataSource >。
<transactionManager >? 有兩種配置方式，分別是JDBC和MANAGED，詳細(xì)說明見配置注釋。
<dataSource > 有三種配置方式，分別是UNPOOLED、POOLED、JNDI，詳細(xì)說明見配置注釋。
<typeAliases>定義別名，使用指定的別名來定義。
注：關(guān)于JNDI的配置，見tomcat的幾種JNDI配置方法
3）mybatis的sql映射配置文件：
[html] view plaincopy
<?xml?version="1.0"?encoding="UTF-8"??>??<!DOCTYPE?mapper?PUBLIC?"-//mybatis.org//DTD?Mapper?3.0//EN"??"http://mybatis.org/dtd/mybatis-3-mapper.dtd">????<mapper?namespace="pageAccessURL"?>????????<!--?????????????cache?-?配置給定命名空間的緩存。????????????cache-ref?–?從其他命名空間引用緩存配置。????????????resultMap?–?最復(fù)雜，也是最有力量的元素，用來描述如何從數(shù)據(jù)庫(kù)結(jié)果集中來加載你的對(duì)象。????????????parameterMap?–?已經(jīng)被廢棄了！老式風(fēng)格的參數(shù)映射。內(nèi)聯(lián)參數(shù)是首選，這個(gè)元素可能在將來被移除。這里不會(huì)記錄。????????????sql?–?可以重用的SQL塊，也可以被其他語句引用。????????????insert?–?映射插入語句????????????update?–?映射更新語句????????????delete?–?映射刪除語句????????????select?–?映射查詢語句??????-->????????????<!--?默認(rèn)不開啟二級(jí)緩存，開啟緩存<cache??eviction="FIFO"?flushInterval="60000"?size="512"?readOnly="true"/>??????????eviction:緩存策略?eviction?=?LRU、FIFO、SOFT、WEAK(默認(rèn)LRU)??????????????1）LRU：最近最少使用的：移除最長(zhǎng)時(shí)間不被使用的對(duì)象??????????????2）FIFO：先進(jìn)先出：按對(duì)象進(jìn)入緩存的順序來移除它們。??????????????3）SOFT：軟引用：移除基于垃圾回收器狀態(tài)和軟引用規(guī)則的對(duì)象。??????????????4）WEAK：弱引用：更積極地移除基于垃圾收集器狀態(tài)和弱引用規(guī)則的對(duì)象。??????????flushInterval：刷新間隔?）可以被設(shè)置為任意的正整數(shù)，而且它們代表一個(gè)合理的毫秒形式的時(shí)間段。???????????默認(rèn)情況是不設(shè)置，也就是沒有刷新間隔，緩存僅僅調(diào)用語句時(shí)刷新。??????????size：引用數(shù)目?可以被設(shè)置為任意正整數(shù)，要記住你緩存的對(duì)象數(shù)目和你運(yùn)行環(huán)境的可用內(nèi)存資源數(shù)目。默認(rèn)值是1024。??????????readOnly：屬性可以被設(shè)置為true或false。只讀的緩存會(huì)給所有調(diào)用者返回緩存對(duì)象的相同實(shí)例。因此這些對(duì)象不能被修改。??????????這提供了很重要的性能優(yōu)勢(shì)?？勺x寫的緩存會(huì)返回緩存對(duì)象的拷貝（通過序列化）。這會(huì)慢一些，但是安全，因此默認(rèn)是false。??????????----------------------------------------------------------------------------------------------??????????使用自定義緩存??????????<cache?type=”com.domain.something.MyCustomCache”>??????????????<property?name=”cacheFile”?value=”/tmp/my-custom-cache.tmp”/>??????????</cache>??????????type屬性指定的類必須實(shí)現(xiàn)org.mybatis.cache.Cache接口??????????----------------------------------------------------------------------------------??????????引用另外的緩存<cache-ref?namespace=”com.someone.application.data.SomeMapper”/>??????-->??????????????????<!--????????????select元素：??????????1）parameterType：參數(shù)類型??????????2）resultType：從這條語句中返回的期望類型的類的完全限定名或別名。??????????注意集合情形，那應(yīng)該是集合可以包含的類型，而不能是集合本身。使用resultType或resultMap，但不能同時(shí)使用。??????????3）resultMap：命名引用外部的resultMap。返回map是MyBatis最具力量的特性，對(duì)其有一個(gè)很好的理解的話，許多復(fù)雜映射的情形就能被解決了。??????????使用resultMap或resultType，但不能同時(shí)使用。??????????4）flushCache：是否清空緩存，默認(rèn)false,不清空，如果為true每次查詢都會(huì)清空緩存。??????????5）useCache：將其設(shè)置為true，將會(huì)導(dǎo)致本條語句的結(jié)果被緩存。默認(rèn)值：true。??????????6）fetchSize：這是暗示驅(qū)動(dòng)程序每次批量返回的結(jié)果行數(shù)。默認(rèn)不設(shè)置（驅(qū)動(dòng)自行處理）。??????????7）statementType：STATEMENT,PREPARED或CALLABLE的一種。這會(huì)讓MyBatis使用選擇使用??????????Statement，PreparedStatement或CallableStatement。默認(rèn)值：PREPARED。??????????8）resultSetType：FORWARD_ONLY|SCROLL_SENSITIVE|SCROLL_INSENSITIVE中的一種。默認(rèn)是不設(shè)置（驅(qū)動(dòng)自行處理）。??????-->??????????????????<select?id="selectPageAccessURL"?parameterType="int"?resultType="pageAccessURL"?>??????????select?*?from?tables?where?URL_ID?=?#{id}??????</select>????????????<select?id="selectPageAccessURLByClass"?parameterType="pageAccessURL"?resultType="pageAccessURL">??????????select?*?from?tables?where?URL_ID?=?#{urlId}?and?URL?=?#{url}??????</select>????????????????<sql?id="usercolumns">URL_ID?as?urlId,url,moduleId,state,mark</sql>??????<select?id="selectPageAccessURL2"?parameterType="int"?resultType="pageAccessURL">??????????select?<include?refid="usercolumns"?/>????????????from?tables?where?URL_ID?=?#{id}??????</select>????????????????????????????<!--????????????resultMap?元素：??????????????1)constructor：類在實(shí)例化時(shí)，用來注入結(jié)果到構(gòu)造方法中??????????????????a)idArg:ID參數(shù)；標(biāo)記結(jié)果作為ID可以幫助提高整體效能??????????????????b)arg:注入到構(gòu)造方法的一個(gè)普通結(jié)果??????????????2)id:一個(gè)ID結(jié)果；標(biāo)記結(jié)果作為ID可以幫助提高整體效能??????????????3)result:注入到字段或JavaBean屬性的普通結(jié)果??????????????4)association:一個(gè)復(fù)雜的類型關(guān)聯(lián)；許多結(jié)果將包成這種類型??????????????5)collection:復(fù)雜類型的集??????????????6)discriminator:使用結(jié)果值來決定使用哪個(gè)結(jié)果映射??????????????????a)case:基于某些值的結(jié)果映射??????????????---------------------------------------------------???????????resultMap下?id、result?元素:??????????????1)property:映射到列結(jié)果的字段或?qū)傩??????????????2)column:從數(shù)據(jù)庫(kù)中得到的列名，或者是列名的重命名標(biāo)簽。這也是通常和會(huì)傳遞給resultSet.getString(columnName)方法參數(shù)中相同的字符串。??????????????3)javaType:一個(gè)Java類的完全限定名，或一個(gè)類型別名（參加上面內(nèi)建類型別名的列表）。如果你映射到一個(gè)JavaBean，MyBatis通?？梢詳喽愋汀??????????????然而，如果你映射到的是HashMap，那么你應(yīng)該明確地指定javaType來保證所需的行為。??????????????4)jdbcType:在這個(gè)表格之后的所支持的JDBC類型列表中的類型。JDBC類型是僅僅需要對(duì)插入，更新和刪除操作可能為空的列進(jìn)行處理。??????????????這是JDBC的需要，而不是MyBatis的。如果你直接使用JDBC編程，你需要指定這個(gè)類型-但僅僅對(duì)可能為空的值。??????????????5)typeHandler:。使用這個(gè)屬性，你可以覆蓋默認(rèn)的類型處理器。這個(gè)屬性值是類的完全限定名或者是一個(gè)類型處理器的實(shí)現(xiàn)，或者是類型別名。??????????resultMap下?constructor?元素：將查詢到的對(duì)象映射到j(luò)avabean時(shí)，如果javabean的構(gòu)造函數(shù)有參數(shù)，則可以使用該元素來指定??????????resultMap下?association?

?
4）測(cè)試方法：
[java] view plaincopy
????public?void?testSelect(){????????????????????try?{??????????????Reader?reader?=?Resources.getResourceAsReader("mybatis-config-mappings.xml");??????????????SqlSessionFactory?sqlSessionFactory?=?new?SqlSessionFactoryBuilder().build(reader,"development1");??????????????SqlSession?session?=?sqlSessionFactory.openSession();??????????????PageAccessURL?pageAccessURL?=(PageAccessURL)session.selectOne("selectPageAccessURL2",?70001);??????????????????????????????????????session.close();??????????????reader.close();??????????????System.out.println(pageAccessURL.getUrl());??????????}?catch?(IOException?e)?{??????????????System.out.println(e);??????????}??????}?? SqlSessionFactory sqlSessionFactory = new SqlSessionFactoryBuilder().build(reader,"development1"); 后面的development1是前面講的數(shù)據(jù)源配置方式之一。如果要測(cè)試jndi的，則要通過容器加載后進(jìn)行。
?
?第二種方式(mybatis3.0+spring3.0，spring自帶的orm中，只有ibatis的，沒有mybatis，所以使用mybatis3和spring整合的話只能用SqlSessionFactory 了)；
1）jar包：
mybatis-3.0.5.jar

spring-web-3.0.5.RELEASE.jar
stripes-1.5.6.jar
commons-dbcp-1.2.2.jar
commons-pool-1.3.jar
junit.jar
2）spring配置文件：
applicationContext.xml
[html] view plaincopy
<?xml?version="1.0"?encoding="UTF-8"??>??<!DOCTYPE?beans?PUBLIC?"-//SPRING//DTD?BEAN//EN"?"http://www.springframework.org/dtd/spring-beans.dtd">????<beans>??????<import?resource="applicationContext-dao.xml"?/>??</beans>?? applicationContext.xml

關(guān)于spring的其他數(shù)據(jù)源配置，這里就不寫了。
?
4）mybatis的配置文件：
[html] view plaincopy
<?xml?version="1.0"?encoding="UTF-8"??>??<!DOCTYPE?configuration?PUBLIC?"-//mybatis.org//DTD?Config?3.0//EN"??"http://mybatis.org/dtd/mybatis-3-config.dtd">????<configuration>??????<settings>????????????????????<setting?name="cacheEnabled"?value="true"/>????????????????????<setting?name="lazyLoadingEnabled"?value="true"/>????????????????????<setting?name="aggressiveLazyLoading"?value="true"/>????????????????????<setting?name="multipleResultSetsEnabled"?value="true"/>????????????????????<setting?name="useColumnLabel"?value="true"/>????????????????????<setting?name="useGeneratedKeys"?value="true"/>????????????????????<setting?name="autoMappingBehavior"?value="PARTIAL"/>????????????????????<setting?name="defaultExecutorType"?value="SIMPLE"/>????????????????????<setting?name="defaultStatementTimeout"?value="25000"/>??????</settings>??????????????????<typeAliases>??????????<typeAlias?alias="pageAccessURL"??type="com.lgm.mybatis.model.PageAccessURL"?/>??????</typeAliases>????????????????????<mappers>??????????<mapper?resource="com/lgm/mybatis/config/pageAccessURL.xml"/>??????</mappers>????</configuration>??
使用了spring管理的話，這里就不用設(shè)置數(shù)據(jù)源等其他配置了
?
5）mybatis的sql映射文件配置：
同方式一配置的sql映射文件配置
?
6）配置DAO層：
[java] view plaincopy
public?class?PageAccessURLManager?{??????????private?SqlSessionFactory?sqlSessionFactory?;????????public?void?setSqlSessionFactory(SqlSessionFactory?sqlSessionFactory)?{??????????this.sqlSessionFactory?=?sqlSessionFactory;??????}????????????public?PageAccessURL?getPageAccessURL(int?url_id){??????????PageAccessURL?page?=?(PageAccessURL)sqlSessionFactory.openSession().selectOne("selectPageAccessURL",url_id);??????????System.out.println(page.getUrl());??????????return?page;??????}??}??
7）測(cè)試：
[java] view plaincopy
public?void?testSelect()?{??????ApplicationContext?tx?=?new?ClassPathXmlApplicationContext("applicationContext.xml");??????PageAccessURLManager?page?=?(PageAccessURLManager)tx.getBean("pageAccessURLManager");??????page.getPageAccessURL(123456);??}??

3）ibatis配置文件：
[html] view plaincopy
<?xml?version="1.0"?encoding="UTF-8"??>??<!DOCTYPE?sqlMapConfig?PUBLIC?"-//iBATIS.com//DTD?SQL?Map?Config?2.0//EN"?"http://www.ibatis.com/dtd/sql-map-config-2.dtd">????<sqlMapConfig>??????<settings?cacheModelsEnabled="true"?enhancementEnabled="true"??????????lazyLoadingEnabled="true"?maxRequests="32"?maxSessions="10"??????????maxTransactions="5"?useStatementNamespaces="false"?/>??????????????????<typeAlias?alias="pageAccessURL"??type="com.lgm.mybatis.model.PageAccessURL"?/>????????????<sqlMap?resource="com/lgm/mybatis/config/pageAccessURL.xml"/>????????</sqlMapConfig>??
4)ibatis的sql映射配置文件：
[html] view plaincopy
<?xml?version="1.0"?encoding="UTF-8"??>??<!DOCTYPE?sqlMap??PUBLIC?"-//iBATIS.com//DTD?SQL?Map?2.0//EN"?"http://www.ibatis.com/dtd/sql-map-2.dtd">??<sqlMap?namespace="pageAccessURL">????????????<cacheModel?id="productCache"?type="LRU">??????????<flushInterval?hours="24"/>??????????<property?name="size"?value="1000"?/>??????</cacheModel>????????<select?id="selectPageAccessURL"?parameterClass="int"?resultClass="pageAccessURL"?cacheModel="productCache">??????????select?*?from?PAGE_ACCESS_URL?where?URL_ID?=?#id#??????</select>????????????<select?id="selectPageAccessURLByClass"?parameterClass="pageAccessURL"?resultClass="pageAccessURL">??????????select?*?from?PAGE_ACCESS_URL?where?URL_ID?=?#urlId#?and?URL?=?#url#??????</select>????????<sql?id="usercolumns">URL_ID?as?urlId,url,moduleId,state,mark</sql>??????<select?id="selectPageAccessURL2"?parameterClass="int"?resultClass="pageAccessURL">??????????select?<include?refid="usercolumns"?/>????????????from?PAGE_ACCESS_URL?where?URL_ID?=?#id#??????</select>????????????<insert?id="insertTest"?>??????????<selectKey?keyProperty="id"?resultClass="int"?>??????????????SELECT?FLOOR(1?+?(RAND()?*?1000000));???????????</selectKey>??????????insert?into?table?values(xx,xx);??????</insert>????</sqlMap>??
5）配置DAO層：
[html] view plaincopy
public?class?PageAccessURLManager?{????????private?SqlMapClient?sqlMapClient?;??????public?void?setSqlMapClient(SqlMapClient?sqlMapClient)?{??????????this.sqlMapClient?=?sqlMapClient;??????}????????????public?void?getPageAccessURL(int?urlId)?throws?SQLException{??????????PageAccessURL?page?=?(PageAccessURL)this.sqlMapClient.queryForObject("selectPageAccessURL",?urlId);??????????System.out.println(page.getUrl());??????}????????????}??
注意：請(qǐng)仔細(xì)對(duì)比mybatis和ibatis的配置區(qū)別。
