springboot+mybatis-plus 两种方式打印sql语句的方法

mybatis-plus:
 mapper-locations: classpath:mapper/*.xml
 configuration:
  log-impl: org.apache.ibatis.logging.stdout.StdOutImpl

​ @Bean("sqlSessionFactory")
  public SqlSessionFactory sqlSessionFactory() throws Exception {
    // 导入mybatissqlsession配置
    MybatisSqlSessionFactoryBean sessionFactory = new MybatisSqlSessionFactoryBean();
    // 指明数据源
    sessionFactory.setDataSource(multipleDataSource(dataSource0(), dataSource1(), dataSource2()));
    // 指明mapper.xml位置(配置文件中指明的xml位置会失效用此方式代替，具体原因未知)
    sessionFactory.setMapperLocations(new PathMatchingResourcePatternResolver().getResources("classpath*:/mapper/**Mapper.xml"));
    // 指明实体扫描(多个package用逗号或者分号分隔)
    sessionFactory.setTypeAliasesPackage("gsa.geographic.system.entity");
    // 导入mybatis配置
    MybatisConfiguration configuration = new MybatisConfiguration();
    configuration.setJdbcTypeForNull(JdbcType.NULL);
    configuration.setMapUnderscoreToCamelCase(true);
    configuration.setCacheEnabled(false);
    // 配置打印sql语句
    configuration.setLogImpl(StdOutImpl.class);
    sessionFactory.setConfiguration(configuration);
    // 添加分页功能
    sessionFactory.setPlugins(new Interceptor[]{
        paginationInterceptor()
    });
    // 导入全局配置
    sessionFactory.setGlobalConfig(globalConfiguration());
    return sessionFactory.getObject();
