【mybatisplus自动填充失败】

几个重要的地方:
1.自动填充代码

@Component
public class MybatisPlusMetaObjectHandler implements MetaObjectHandler {

     @Override
     public void insertFill(MetaObject metaObject) {
         log.info("insert fill data ... ");
         this.strictInsertFill(metaObject, "createTime", Date.class, new Date());
         this.strictUpdateFill(metaObject, "updateTime", Date.class, new Date());
         this.strictInsertFill(metaObject, "isDel", Integer.class, DeletedTypeEnum.NO.getCode());
     }

     @Override
     public void updateFill(MetaObject metaObject) {
         log.info("update fill data ... ");
         String currentUserId = getCurrentUserId();
         this.strictUpdateFill(metaObject, "updateTime", Date.class, new Date());
         this.strictUpdateFill(metaObject, "updater", String.class, currentUserId);
         this.strictUpdateFill(metaObject, "updateUser", String.class, currentUserId);
     }
}

2.字段注解

/**
 * 插入时
*/
@TableField(value = "create_time", fill = FieldFill.INSERT)
private Date createTime;
/**
 * 插入和更新时
*/
@TableField(value = "update_time", fill = FieldFill.INSERT_UPDATE)
private Date updateTime;

3.配置, 部分代码

/**
 * SqlSessionFactory
 */
@Bean(name = "sqlSessionFactory")
public SqlSessionFactory getSqlSessionFactory() throws Exception {
    MybatisSqlSessionFactoryBean factoryBean = new MybatisSqlSessionFactoryBean();
    // 全局配置
    GlobalConfig globalConfig = GlobalConfigUtils.defaults();
    globalConfig.setMetaObjectHandler(new MybatisPlusMetaObjectHandler());
    factoryBean.setGlobalConfig(globalConfig);

    return factoryBean.getObject();
}

4.如果配置了乐观锁, 第一步的代码会失败, 自动填充使用下面的

if (metaObject.hasGetter("updateTime")) {
  this.fillStrategy(metaObject, "updateTime", new Date());
}
if (metaObject.hasGetter("updateTime")) {
    this.fillStrategy(metaObject, "updateTime", new Date());
}
