为了快速开发,需要把之前的老项目升级为mybatis-plus
步骤一:导入jar包
步骤二:删除mybatis-spring桥梁包
一定要删除之前与mybatis相关的包,否则可能会报错
步骤三:添加配置参数
mybatis-plus.mapper-locations=classpath:mapper/*.xmlmybatis-plus.global-config.db-config.field-strategy=not_emptymybatis-plus.global-config.db-config.id-type=input#mybatis-plus.configuration.map-underscore-to-camel-case=truemybatis-plus.configuration.log-impl=org.apache.ibatis.logging.stdout.StdOutImplmybatis-plus.configuration.call-setters-on-nulls=true
步骤四:添加java配置对象
package com.XXXXX.biz.config;
import com.baomidou.mybatisplus.autoconfigure.SpringBootVFS;
import com.baomidou.mybatisplus.core.config.GlobalConfig;
import com.baomidou.mybatisplus.extension.incrementer.OracleKeyGenerator;
import com.baomidou.mybatisplus.extension.plugins.PaginationInterceptor;
import com.baomidou.mybatisplus.extension.spring.MybatisSqlSessionFactoryBean;
import com.github.pagehelper.PageInterceptor;
import org.apache.ibatis.io.VFS;
import org.apache.ibatis.session.SqlSessionFactory;
import org.mybatis.spring.annotation.MapperScan;
import org.springframework.context.annotation.Bean;
import org.springframework.context.annotation.Configuration;
import org.springframework.core.io.support.PathMatchingResourcePatternResolver;
import org.springframework.transaction.annotation.EnableTransactionManagement;
import javax.sql.DataSource;

@Configuration
@MapperScan(basePackages = {"com.qianxingniwo.biz.mapper"})
@EnableTransactionManagement
public class MybatisPlusConfig {
/**
* 分页插件
*/
@Bean
public PaginationInterceptor paginationInterceptor() {
return new PaginationInterceptor();
}
/**
* pagehelper的分页插件
*/
@Bean
public PageInterceptor pageInterceptor() {
return new PageInterceptor();
}
@Bean
public SqlSessionFactory sqlSessionFactory(DataSource dataSource) throws Exception {
String mapperLocations = "classpath:mapper/*.xml";
VFS.addImplClass(SpringBootVFS.class);
final MybatisSqlSessionFactoryBean sessionFactory = new MybatisSqlSessionFactoryBean();
sessionFactory.setDataSource(dataSource);
sessionFactory.setMapperLocations(new PathMatchingResourcePatternResolver().getResources(mapperLocations));
// 配置组件生成策略
sessionFactory.setGlobalConfig(globalConfig());
return sessionFactory.getObject();
}
@Bean
public GlobalConfig globalConfig() {
GlobalConfig conf = new GlobalConfig();
conf.setDbConfig(new GlobalConfig.DbConfig().setKeyGenerator(new OracleKeyGenerator()));
return conf;
}
}
到这里大家就可以使用mybatis-plus了
