java - 使用 Spring MVC 通过 AJAX 发送 HTML 数据

Question

我有一个 AJAX 调用，该调用已被处理，并且 Spring 返回一个 jsp 页面。

@RequestMapping(value = "/getData.do")
public String getData() {
    // ...
    return "data";
}

我回来了 data.jsp .

AJAX 调用如下所示:

$.ajax({
    type : 'GET',
    url : "getData.do",

    error : function() {
        alert('failure');
    },
    success : function(result) {
        alert("Success");
    }
});

我在web.xml中有servlet映射对于 .do文件

  <servlet-mapping>
    <servlet-name>spring</servlet-name>
    <url-pattern>*.do</url-pattern>
  </servlet-mapping>

好的，当我有这个 <bean> 时在我的调度程序中定义，它工作正常。

<bean class="org.springframework.web.servlet.view.InternalResourceViewResolver">
   <property name="prefix" value="/WEB-INF/jsp/"/>
   <property name="suffix" value=".jsp"/>
</bean>

但是，当我将其更改为这个时，它失败了!

<bean class="org.springframework.web.servlet.view.ContentNegotiatingViewResolver">
  <property name="mediaTypes">
    <map>
      <entry key="html" value="text/html"/>
      <entry key="json" value="application/json"/>
    </map>
  </property>
  <property name="viewResolvers">
    <list>
      <bean class="org.springframework.web.servlet.view.BeanNameViewResolver"/>
      <bean class="org.springframework.web.servlet.view.InternalResourceViewResolver">
        <property name="prefix" value="/WEB-INF/jsp/"/>
        <property name="suffix" value=".jsp"/>
      </bean>
    </list>
  </property>
  <property name="defaultViews">
    <list>
      <bean class="org.springframework.web.servlet.view.json.MappingJackson2JsonView" />
    </list>
  </property>
</bean>

我需要这个 JSON。有什么想法吗？

更新:添加堆栈跟踪

Answer 1

当我修改 AJAX 中的 Accept header (如本文 Pass accepts header parameter to jquery ajax 中所述)时，它得到了修复。 .

更新了 AJAX:

$.ajax({
    type : 'GET',
    url : "getData.do",
    headers: {          
        Accept : "text/html; charset=utf-8",         
    },    
    error : function() {
        alert('failure');
    },
    success : function(result) {
        alert("Success");
    }
});
