mybatis plus簡介

詳見mybatis plus的官網(wǎng)

業(yè)務要求

業(yè)務上要求存儲數(shù)據(jù)的時候根據(jù)某個字段動態(tài)的選擇數(shù)據(jù)要存儲的表.

如根據(jù)code字段: code->[1001,1002]來進行選擇存儲的表:

經(jīng)過下面的配置實現(xiàn)動態(tài)表名如 --> table1_1001,table_1002的效果.以此動態(tài)生成表名的效果.

具體實現(xiàn)

MPConfig.java

import com.alibaba.fastjson.JSON;

import com.alibaba.fastjson.JSONObject;

import com.baomidou.mybatisplus.extension.parsers.DynamicTableNameParser;

import com.baomidou.mybatisplus.extension.parsers.ITableNameHandler;

import com.baomidou.mybatisplus.extension.plugins.PaginationInterceptor;

import org.apache.ibatis.reflection.MetaObject;

import org.mybatis.spring.annotation.MapperScan;

import org.springframework.beans.factory.annotation.Autowired;

import org.springframework.context.annotation.Bean;

import org.springframework.context.annotation.Configuration;

import java.util.Collections;

import java.util.HashMap;

import java.util.List;

@Configuration

@MapperScan("com.dao")

public class MPConfig {

@Autowired

private Tables tableNames;

/**

* 動態(tài)表名

*/

@Bean

public PaginationInterceptor paginationInterceptor(){

PaginationInterceptor paginationInterceptor = new PaginationInterceptor();

DynamicTableNameParser dynamicTableNameParser = new DynamicTableNameParser();

dynamicTableNameParser.setTableNameHandlerMap(new HashMap(2){{

//涉及表集合

List tables = tableNames.getTableNames();

//動態(tài)表規(guī)則 初始表名+_+code

tables.forEach(tableTitle -> put(tableTitle,(metaObject, sql, tableName) -> tableName + "_" + String.valueOf(getParamValue("關(guān)鍵字段名",metaObject))));

}});

paginationInterceptor.setSqlParserList(Collections.singletonList(dynamicTableNameParser));

return paginationInterceptor;

}

/**

* @Author: xuzz

* @Date: 下午2:55 19-10-12

* 獲取參數(shù)值

*/

private Object getParamValue(String title, MetaObject metaObject){

//獲取參數(shù)

Object originalObject = metaObject.getOriginalObject();

JSONObject originalObjectJSON = JSON.parseObject(JSON.toJSONString(originalObject));

JSONObject boundSql = originalObjectJSON.getJSONObject("boundSql");

JSONObject parameterObject = boundSql.getJSONObject("parameterObject");

return parameterObject.get(title);

}

Tables.java 表頭列表類

@Configuration

@ConfigurationProperties("mp")

public class Tables {

private List tableNames;

public List getTableNames() {

return tableNames;

}

public void setTableNames(List tableNames) {

this.tableNames = tableNames;

}

}

application.yml

mp:

tableNames: #表頭列表

- table1

- table2

- table3

其他基礎(chǔ)配置的無異
