java - 已经有 'controllers' bean方法

Question

我的调度程序-servlet.xml

<?xml version="1.0" encoding="UTF-8"?>
<beans xmlns="http://www.springframework.org/schema/beans"
       xmlns:xsi="http://www.w3.org/2001/XMLSchema-instance"
       xmlns:context="http://www.springframework.org/schema/context"
       xmlns:mvc="http://www.springframework.org/schema/mvc"
       xsi:schemaLocation="http://www.springframework.org/schema/beans
       http://www.springframework.org/schema/beans/spring-beans.xsd
       http://www.springframework.org/schema/context
       http://www.springframework.org/schema/context/spring-context-3.0.xsd http://www.springframework.org/schema/mvc http://www.springframework.org/schema/mvc/spring-mvc.xsd">

    <context:component-scan base-package = "mvc"/>
    <bean class = "org.springframework.web.servlet.view.InternalResourceViewResolver">
        <property name = "prefix" value = "/WEB-INF/pages/" />
        <property name = "suffix" value = ".jsp" />
    </bean>

    <bean id = "dataSource" class = "org.springframework.jdbc.datasource.DriverManagerDataSource">
        <property name = "driverClassName" value = "oracle.jdbc.driver.OracleDriver" />
        <property name = "url" value = "jdbc:oracle:thin:@localhost:1521:XE" />
        <property name = "username" value = ""/>
        <property name = "password" value = ""/>
    </bean>

    <bean id = "jdbcTemplate" class = "org.springframework.jdbc.core.JdbcTemplate">
        <property name = "dataSource" ref = "dataSource"/>
    </bean>

    <bean id = "dao" class = "mvc.dao.DAOImpl">
        <property name = "template" ref = "jdbcTemplate"/>
    </bean>
</beans>

为了使用 REST，我需要 <mvc:annotation-driven/> 。但是将其添加到dispatcher-servlet.xml后，我得到“已经有' Controller 'bean方法”。
Controller 类在这里 http://collabedit.com/hfrv8
DAOimpl 类在这里 http://collabedit.com/dms4s

问题可能出在哪里？

Answer 1

嗯，问题出在具有相同注释 @RequestMapping("/viewAll1") 的 Controllers 类的多个方法中。评论完所有内容后，错误消失了
