【发布时间】：2016-01-15 20:41:35
【问题描述】：

我是这个概念的新手，我不明白错误是什么，所以有人帮我纠正这个错误。我在我的 xml 中使用与我的 pom 文件中相同的版本。（我使用的是 maven，spring boot 和 eclipse 之间）。

错误是

【问题讨论】：

你在 pom 中使用 spring beans 配置？

标签： java maven spring-boot

【解决方案1】：

您已将 bean 添加到 pom.xml，而应该将其添加到 spring.xml。你的 POM 应该是这样的

你的 spring.xml 应该是这样的：

   http://www.springframework.org/schema/mvc

    <property name="prefix" value="/WEB-INF/views/" />
    <property name="suffix" value=".jsp" />
</bean>

【解决方案2】：

移除弹簧配置：

    <beans xmlns="http://www.springframework.org/schema/beans"
       xmlns:xsi="http://www.w3.org/2001/XMLSchema-instance"
       xmlns:p="http://www.springframework.org/schema/p"

    <context:component-scan base-package="com.example.springmvcforms" />
    <mvc:resources mapping="/resources/**" location="/resources/" />
    <mvc:annotation-driven />

    <bean id="viewResolver" class="org.springframework.web.servlet.view.InternalResourceViewResolver">

        <property name="prefix" value="/WEB-INF/views/" />
        <property name="suffix" value=".jsp" />
    </bean>
</beans>

从你的 pom 中并把它放到一个新的 XML 文件中
