[笔记] 解决插件 Hibernate for Eclipse生成的hbm.xml 无法显示中文问题

 

参考文章 http://www.blogjava.net/pauliz/archive/2009/11/13/302162.html

经实际操作总结如下

☆适用于Eclipse4.4及以下版本;

☆更高版本未测试,估计可行;

☆ Eclipse4.4需要修改两个目录下的文件;

☆本文以 hibernate-tools-3.4.0.CR2.jar为例

 

1.    安装Hibernate Tools插件

2.    解压文件--- hibernate-tools-3.4.0.CR2.jar

X:\Eclipse\plugins\org.hibernate.eclipse.libs_3.7.1.Final-v20140303-0022-B124\lib\tools\hibernate-tools-3.4.0.CR2.jar

或

X:\Eclipse \plugins\org.hibernate.eclipse.libs_4.0.1.Final-v20150324-2307-B95\lib\tools\hibernate-tools-3.4.0.CR2.jar

3.    修改文件

3.1 修改hibernate-tools-3.4.0.CR2\pojo\

3.3 修改 hibernate-tools-3.4.0.CR2\org\hibernate\tool\hbm2x\

TemplateProducer.class (需要自己先搭建环境再修改)

·创建JAVA项目

·引入2个jar包   hibernate-tools-3.4.0.CR2.jar    org.apache.commons.logging_xxxxx.jar

·反编译.class      \hibernate-tools-3.4.0.CR2\org\hibernate\tool\hbm2x\TemplateProducer.class

·创建javal类 TemplateProducer.java
