嵌套异常是java.lang.ClassNotFoundException：org.springframework.web.servlet.view.json.JsonView

Question

我有一个弹簧web应用程序，我需要运行json服务。

下面是我的程序的调度器 - 小服务程序。

<?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:p="http://www.springframework.org/schema/p" 
    xmlns:context="http://www.springframework.org/schema/context" 
    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.xsd"> 

    <!-- SPECIFIC CONFIGURATIONS --> 
    <import resource="springConfigurations/common-config.xml"/> 
    <import resource="springConfigurations/mvc-config.xml"/> 

    <!-- COMMON CONFIGURATIONS --> 
    <bean class="org.springframework.web.servlet.mvc.annotation.DefaultAnnotationHandlerMapping" /> 
    <bean class="org.springframework.web.servlet.mvc.annotation.AnnotationMethodHandlerAdapter" /> 
    <bean class="org.springframework.web.servlet.mvc.support.ControllerClassNameHandlerMapping" /> 

    <bean name="viewResolver" class="org.springframework.web.servlet.view.XmlViewResolver"> 
     <property name="location"> 
      <value>/WEB-INF/views.xml</value> 
     </property> 
     <property name="order"> 
      <value>1</value> 
     </property> 
    </bean> 

</beans> 

而这是views.xml代码。

<beans xmlns="http://www.springframework.org/schema/beans" 
    xmlns:xsi="http://www.w3.org/2001/XMLSchema-instance" 
    xsi:schemaLocation="http://www.springframework.org/schema/beans 
    http://www.springframework.org/schema/beans/spring-beans-3.2.xsd"> 

    <bean name="jsonView" class="org.springframework.web.servlet.view.json.JsonView"/> 

</beans> 

我得到了我的问题说头控制台下面的错误。

我添加了所有必需的JAR文件，但仍出现错误。请帮助我解决这个问题！

Answer 1

你没有所有必需的罐子。请转至this maven page，下载JAR或使用pom依赖项。当您编译并运行您的应用程序时，将jar添加到您的类路径中
