启动dubbo时一直重复报这个warning，报到最后抛错：
（同样错误的另外一种表现 Type handler was null on parameter mapping for property 'createTime'）

发现对象属性使用LocalDateTime这是jdk8的新属性
之前项目依赖为：
<!--用于处理mybatis与java8中的localDate的sql映射--><dependency><groupId>org.mybatis</groupId><artifactId>mybatis-typehandlers-jsr310</artifactId><version>1.0.1</version></dependency><dependency><groupId>com.fasterxml.jackson.datatype</groupId><artifactId>jackson-datatype-jsr310</artifactId></dependency>
加了还是会报，遂改为：
<!--LocalDateTime-->
<dependency><groupId>com.fasterxml.jackson.datatype</groupId><artifactId>jackson-datatype-jsr310</artifactId><version>2.9.2</version>
</dependency>
<dependency><groupId>org.mybatis</groupId><artifactId>mybatis-typehandlers-jsr310</artifactId><version>1.0.2</version>
</dependency>正常启动，大概是依赖关系错误吧，包冲突之类的问题。
后续：
由于其他模块也有LocalDateTime，pom文件这个版本又不起作用了，遂升级了mybatis版本。
如果不想加入新的依赖，也不想加入配置文件，则只需要将mybatis升级到3.4.6，将mybatis-spring的版本是升级到1.3.2即可，此时可以直接支持JDK1.8的日期类型。
<dependency><groupId>org.mybatis</groupId><artifactId>mybatis</artifactId><version>3.4.6</version>
</dependency><dependency><groupId>org.mybatis</groupId><artifactId>mybatis-spring</artifactId><version>1.3.2</version>
</dependency>
