springboot+mybatisplus 报 Invalid bound statement (not found)异常

static final String MAPPER_LOCATION = "classpath*:mappings*.xml";

	@Bean(name = "masterSqlSessionFactory")
	@Primary
	public SqlSessionFactory masterSqlSessionFactory(@Qualifier("dataSource") DataSource masterDataSource)
			throws Exception {
		//大坑，mybatis-plus得用 MybatisSqlSessionFactoryBean 否则报 Invalid bound statement (not found)
		//final SqlSessionFactoryBean sessionFactory = new SqlSessionFactoryBean();
		final MybatisSqlSessionFactoryBean sessionFactory = new MybatisSqlSessionFactoryBean();
		sessionFactory.setMapperLocations(new PathMatchingResourcePatternResolver()
				.getResources(DruidDBConfig.MAPPER_LOCATION)	//查看mapper.xml配置路径是否正确（也是坑）
		);
		sessionFactory.setDataSource(masterDataSource);
		return sessionFactory.getObject();
