mybatis-demo's Introduction

工程简介

Aliyun Java Initializr

这是一个测试 mybatis 的项目。

  1. 延迟加载出现错误

application.properties lazy-loading-enabled=true cause an error

nested exception is org.apache.ibatis.executor.ExecutorException: Error creating lazy proxy.  Cause: java.lang.RuntimeException: icu.guodapeng.mybatisdemo.domain.entity.UserBase is final
org.mybatis.spring.MyBatisSystemException: nested exception is org.apache.ibatis.executor.ExecutorException: Error creating lazy proxy.  Cause: java.lang.RuntimeException: icu.guodapeng.mybatisdemo.domain.entity.UserBase is final
	at org.mybatis.spring.MyBatisExceptionTranslator.translateExceptionIfPossible(MyBatisExceptionTranslator.java:96)
	at org.mybatis.spring.SqlSessionTemplate$SqlSessionInterceptor.invoke(SqlSessionTemplate.java:441)
	...

Test

解决了方案：使用 kotlin-allopen 插件解决。与 CGLIB 的工作方式有关。

kotlin allopen
