Mybatis下完整sql输出

通过Mybatis下的@Intercepts拦截器注解 实现完整sql输出

新建sql拦截器

增加Mybatis拦截器配置

• mybatis-config.xml中

<?xml version="1.0" encoding="UTF-8"?>
<!DOCTYPE configuration PUBLIC "-//mybatis.org//DTD SQL Map Config 3.0//EN"
		"http://mybatis.org/dtd/mybatis-3-config.dtd">
<configuration>
	<typeAliases>
	</typeAliases>
	<!-- 拦截器配置开始 -->
	<plugins>
		<plugin interceptor="com.zhitengda.web.interceptor.MybatisSqlOutInterceptor" />
	</plugins>
	<mappers>
	</mappers>
</configuration>
