防止mybatis generator追加生成xml

mybatis generator默认采用追加方式生成。用过就知道，麻烦。更希望覆盖。

怎么办？

1.建一个类

public class OverwriteXmlPluginextends PluginAdapter {

@Override

    public boolean validate(List warnings) {

return true;

}

@Override

    public boolean sqlMapGenerated(GeneratedXmlFile sqlMap, IntrospectedTable introspectedTable) {

try {

Field field = sqlMap.getClass().getDeclaredField("isMergeable");

field.setAccessible(true);

field.setBoolean(sqlMap,false);

}catch (Exception e) {

e.printStackTrace();

}

return true;

}

}

2.修改xml配置

<context id="DB2Tables" targetRuntime="MyBatis3">

<property name="autoDelimitKeywords" value="true"/>

<property name="beginningDelimiter" value="`"/>

<property name="endingDelimiter" value="`"/>

<plugin type="com.main.fintech.util.OverwriteXmlPlugin"/>

<!--原来是下面这个，增加上面的。完事-->

<plugin type=" org.mybatis.generator.plugins.SerializablePlugin "/>
