SpringMVC配置
<!-- 可以扫描controller、service、...-->
<context:component-scan base-package="ynnu.zmf.*"/>
<mvc:annotation-driven/>
<context:annotation-config />
<import resource="applicationContext-dao.xml" />
<import resource="applicationContext-transaction.xml"/>
<bean
class="org.springframework.web.servlet.view.InternalResourceViewResolver">
<!-- 配置jsp路径的前缀 -->
<property name="prefix" value="/jsp/"/>
<!-- 配置jsp路径的后缀 -->
<property name="suffix" value=".jsp"/>
</bean>
问题已经解决，解决办法就是在controller层加上@responsebody
出现啥？你怎么没描述完整
web.xml如何配置的？
