In localhost execution of the project, I'm encountering an 'Invalid bound statement (not found)' error

Question

The error message is as follows,

An error occurred while running this line of code:

SysRoleService:

Even after attempting 'mvn clean' and clearing the 'target' folder, the error persists.

============= Bug has been fixed! =============================

The issue lies within the configuration class. The YAML file in Nacos gets overridden when I create a new MybatisSqlSessionFactoryBean.

@Bean
public SqlSessionFactory sqlSessionFactory(DataSource dataSource) throws Exception {
    MybatisSqlSessionFactoryBean mybatisSqlSessionFactoryBean = new MybatisSqlSessionFactoryBean();
    //获取mybatis-plus全局配置
    GlobalConfig globalConfig = GlobalConfigUtils.defaults();
    //mybatis-plus全局配置设置元数据对象处理器为自己实现的那个
    globalConfig.setMetaObjectHandler(new AutoFillHandler());
    mybatisSqlSessionFactoryBean.setDataSource(dataSource);
    //mybatisSqlSessionFactoryBean关联设置全局配置
    mybatisSqlSessionFactoryBean.setGlobalConfig(globalConfig);
    return mybatisSqlSessionFactoryBean.getObject();
}

Setting the MapperLocations resolves the problem.

// 设置 Mapper 文件的位置
Resource[] resources = new PathMatchingResourcePatternResolver().getResources("classpath:mappers/*Mapper.xml");
mybatisSqlSessionFactoryBean.setMapperLocations(resources);
