MetaObjectHandler not found

MetaObjectHandler not found是一个常见的错误，通常出现在使用Mybatis-Plus的时候。这个错误的原因是没有正确配置Mybatis-Plus的MetaObjectHandler。

解决这个问题的方法是在MybatisSqlSessionFactoryBean的配置中添加MetaObjectHandler。根据提供的引用内容，可以看到在第一次配置MybatisSqlSessionFactoryBean时，没有设置MetaObjectHandler的相关配置，导致错误的发生。下面是一个正确的配置示例：

@Autowired
private MybatisPlusProperties mybatisPlusProperties;

@Bean
public SqlSessionFactory sqlSessionFactory() throws Exception {
MybatisSqlSessionFactoryBean sqlSessionFactoryBean = new MybatisSqlSessionFactoryBean();
sqlSessionFactoryBean.setDataSource(dataSource());

MybatisConfiguration configuration = new MybatisConfiguration();
configuration.setMapUnderscoreToCamelCase(true);
configuration.setDefaultEnumTypeHandler(EnumOrdinalTypeHandler.class);
sqlSessionFactoryBean.setConfiguration(configuration);

sqlSessionFactoryBean.setPlugins(new Interceptor[]{paginationInnerInterceptor()});

Resource[] resources = mybatisPlusProperties.resolveMapperLocations();
sqlSessionFactoryBean.setMapperLocations(resources);

sqlSessionFactoryBean.setMetaObjectHandler(metaObjectHandler()); // 添加MetaObjectHandler配置

return sqlSessionFactoryBean.getObject();
}

@Bean
public MetaObjectHandler metaObjectHandler() {
return new YourMetaObjectHandler(); // 替换为自定义的MetaObjectHandler类
}

这样配置后，就能正确加载MetaObjectHandler，解决MetaObjectHandler not found的问题。请注意将YourMetaObjectHandler替换为自己定义的MetaObjectHandler类。<span class="em">1</span><span class="em">2</span><span class="em">3</span>
