這篇文章主要介紹了mybatis項目兼容mybatis-plus問題,具有很好的參考價值,希望對大家有所幫助,如有錯誤或未考慮完全的地方,望不吝賜教

1、添加mybatis-plus依賴

        <dependency>
            <groupId>com.baomidou</groupId>
            <artifactId>mybatis-plus-boot-starter</artifactId>
            <version>3.5.1</version>
        </dependency>
        <dependency>
            <groupId>com.baomidou</groupId>
            <artifactId>mybatis-plus-extension</artifactId>
            <version>3.5.1</version>
        </dependency>

2、將環(huán)境配置yml里的mybatis配置名稱

修改成mybatis-plus：

mybatis-plus:
    # 搜索指定包別名
    typeAliasesPackage: com.cartreasure.**.domain
    # 配置mapper的掃描，找到所有的mapper.xml映射文件
    mapperLocations: classpath*:mapper/**/*Mapper.xml
    # 加載全局的配置文件
    configLocation: classpath:mybatis/mybatis-config.xml
    configuration:
        map-underscore-to-camel-case: true

3、修改MyBatisConfig.java類

里的sqlSessionFactory方法中獲取的屬性參數(shù)由mybatis改成mybatis-plus

并在結(jié)尾添加mybatis-plus的全局配置

 @Bean
    public SqlSessionFactory sqlSessionFactory(DataSource dataSource) throws Exception
    {
        String typeAliasesPackage = env.getProperty("mybatis-plus.typeAliasesPackage");
        String mapperLocations = env.getProperty("mybatis-plus.mapperLocations");
        String configLocation = env.getProperty("mybatis-plus.configLocation");
        typeAliasesPackage = setTypeAliasesPackage(typeAliasesPackage);
        VFS.addImplClass(SpringBootVFS.class);
 
        final MybatisSqlSessionFactoryBean sessionFactory = new MybatisSqlSessionFactoryBean();
        sessionFactory.setDataSource(dataSource);
        sessionFactory.setTypeAliasesPackage(typeAliasesPackage);
        sessionFactory.setMapperLocations(resolveMapperLocations(StringUtils.split(mapperLocations, ",")));
        sessionFactory.setConfigLocation(new DefaultResourceLoader().getResource(configLocation));
 
        //獲取mybatis-plus全局配置
        GlobalConfig globalConfig = GlobalConfigUtils.defaults();
        globalConfig.setMetaObjectHandler(new MyMetaObjectHandler());
        GlobalConfig.DbConfig dbConfig = new GlobalConfig.DbConfig();
        dbConfig.setLogicDeleteField("delFlag");
        dbConfig.setLogicDeleteValue("2");
        globalConfig.setDbConfig(dbConfig);
        sessionFactory.setGlobalConfig(globalConfig);
 
        MybatisPlusInterceptor interceptor = new MybatisPlusInterceptor();
        interceptor.addInnerInterceptor(new PaginationInnerInterceptor(DbType.MYSQL));
        sessionFactory.setPlugins(interceptor);
 
        return sessionFactory.getObject();
    }

 
import com.baomidou.mybatisplus.core.handlers.MetaObjectHandler;
import com.cartreasure.common.utils.SecurityUtils;
import org.apache.ibatis.reflection.MetaObject;
import org.springframework.stereotype.Component;
 
/**
 * mybatis-plus自動填充
 */
@Component
public class MyMetaObjectHandler implements MetaObjectHandler {
    @Override
    public void insertFill(MetaObject metaObject) {
        this.strictInsertFill(metaObject,"createBy",String.class, SecurityUtils.getLoginUser().getUsername());
    }
 
    @Override
    public void updateFill(MetaObject metaObject) {
        this.strictUpdateFill(metaObject,"updateBy",String.class,SecurityUtils.getLoginUser().getUsername());
    }
}
