spring boot 1.4默認(rèn)使用 hibernate validator 5.2.4 Final實(shí)現(xiàn)校驗(yàn)功能。hibernate validator 5.2.4 Final是JSR 349 Bean Validation 1.1的具體實(shí)現(xiàn)。

How to disable Hibernate validation in a Spring Boot project

As [M. Deinum] mentioned in a comment on my original post, the solution is to set:

spring.jpa.properties.javax.persistence.validation.mode=none
In the application.properties file.

Additionally, this behaviour is described here (its easy to miss because no example is provided).

http://stackoverflow.com/questions/26764532/how-to-disable-hibernate-validation-in-a-spring-boot-project


一 初步使用
hibernate vilidator主要使用注解的方式對(duì)bean進(jìn)行校驗(yàn)，初步的例子如下所示：

package com.query; import javax.validation.constraints.Min; import org.hibernate.validator.constraints.NotBlank; public class Student { //在需要校驗(yàn)的字段上指定約束條件 @NotBlankprivate String name;@Min(3)private int age;@NotBlankprivate String classess;public String getName() {return name;}public void setName(String name) {this.name = name;}public int getAge() {return age;}public void setAge(int age) {this.age = age;}public String getClassess() {return classess;}public void setClassess(String classess) {this.classess = classess;}}

?

然后在controller中可以這樣調(diào)用，加上@Validated注解即可。

package com.controller; import org.springframework.validation.annotation.Validated; import org.springframework.web.bind.annotation.RequestMapping; import org.springframework.web.bind.annotation.RestController;import com.learn.validate.domain.Student;@RestController public class ValidateController {@RequestMapping(value="testStudent")public void testStudent(@Validated Student student) {} } 如果校驗(yàn)失敗，默認(rèn)會(huì)返回Spring boot 框架的出錯(cuò)信息。是一個(gè)json串，里面有詳細(xì)的出錯(cuò)描述。

二 使用gruops 屬性來實(shí)現(xiàn)區(qū)別不同的校驗(yàn)需求
在上面的例子中，如果Student bean想要用于兩個(gè)不同的請(qǐng)求中，每個(gè)請(qǐng)求有不同的校驗(yàn)需求，例如一個(gè)請(qǐng)求只需要校驗(yàn)name字段,一個(gè)請(qǐng)求需要校驗(yàn)name和age兩個(gè)字段，那該怎么做呢？
使用注解的groups屬性可以很好的解決這個(gè)問題,如下所示：

package com.query; import javax.validation.constraints.Min;import org.hibernate.validator.constraints.NotBlank;public class Student {//使用groups屬性來給分組命名，然后在需要的地方指定命令即可@NotBlank(groups=NAME.class)private String name;@Min(value=3,groups=AGE.class)private int age;@NotBlankprivate String classess;public String getName() {return name;}public void setName(String name) {this.name = name;}public int getAge() {return age;}public void setAge(int age) {this.age = age;}public String getClassess() {return classess;}public void setClassess(String classess) {this.classess = classess;}public interface NAME{};public interface AGE{};}

?

根據(jù)需要在@Validated屬性中指定需要校驗(yàn)的分組名，可以指定1到多個(gè)。指定到的分組名會(huì)全部進(jìn)行校驗(yàn)，不指定的不校驗(yàn)。

package com.controller;import org.springframework.validation.annotation.Validated; import org.springframework.web.bind.annotation.RequestMapping; import org.springframework.web.bind.annotation.RestController;import com.learn.validate.domain.Student; import com.learn.validate.domain.Student.AGE; import com.learn.validate.domain.Student.NAME;@RestController public class ValidateController {@RequestMapping(value="testStudent")public void testStudent(@Validated Student student) {}@RequestMapping(value="testStudent1")public void testStudent1(@Validated(NAME.class) Student student) {}@RequestMapping(value="testStudent2")public void testStudent2(@Validated({NAME.class,AGE.class}) Student student) {} }

三 使用 @ScriptAssert 注解校驗(yàn)復(fù)雜的業(yè)務(wù)邏輯
如果需要校驗(yàn)的業(yè)務(wù)邏輯比較復(fù)雜，簡(jiǎn)單的@NotBlank，@Min注解已經(jīng)無法滿足需求了，這時(shí)可以使用@ScriptAssert來指定進(jìn)行校驗(yàn)的方法，通過方法來進(jìn)行復(fù)雜業(yè)務(wù)邏輯的校驗(yàn)，然后返回 true或false來表明是否校驗(yàn)成功。
例如下面的例子：

package com.query; import javax.validation.constraints.Min;import org.hibernate.validator.constraints.NotBlank; import org.hibernate.validator.constraints.ScriptAssert;import com.learn.validate.domain.Student.CHECK; //通過script 屬性指定進(jìn)行校驗(yàn)的方法，傳遞校驗(yàn)的參數(shù)， //依然可以通過groups屬性指定分組名稱 @ScriptAssert(lang="javascript",script="com.learn.validate.domain .Student.checkParams(_this.name,_this.age,_this.classes)", groups=CHECK.class) public class Student {@NotBlank(groups=NAME.class)private String name;@Min(value=3,groups=AGE.class)private int age;@NotBlankprivate String classess;public String getName() {return name;}public void setName(String name) {this.name = name;}public int getAge() {return age;}public void setAge(int age) {this.age = age;}public String getClassess() {return classess;}public void setClassess(String classess) {this.classess = classess;}public interface NAME{};public interface AGE{};public interface CHECK{};//注意進(jìn)行校驗(yàn)的方法要寫成靜態(tài)方法，否則會(huì)出現(xiàn) //TypeError: xxx is not a function 的錯(cuò)誤public static boolean checkParams(String name,int age,String classes) {if(name!=null&&age>8&classes!=null){return true;}else{return false;}}} 在需要的地方，通過分組名稱進(jìn)行調(diào)用 package com.controller;import org.springframework.validation.annotation.Validated; import org.springframework.web.bind.annotation.RequestMapping; import org.springframework.web.bind.annotation.RestController;import com.learn.validate.domain.Student; import com.learn.validate.domain.Student.CHECK;@RestController public class ValidateController {@RequestMapping(value="testStudent3")public void testStudent3(@Validated(CHECK.class) Student student) {} }
