问题还是出在配置上面:springmvc-config.xml

之前费了九牛二虎之力解决了所有报错的配置,并不好用:

下面是这个不能用的版本

<?xml version="1.0" encoding="UTF-8"?>
<beans xmlns="http://www.springframework.org/schema/beans"

<!-- spring自动扫描base-pack下面的包和子包内的java文件，如果发现有相关注释的类，则注册为bean -->
<context:component-scan base-package="org.fkit" />
<!-- 配置annotation类型的处理器映射器 -->
<bean class="org.springframework.web.servlet.mvc.method.annotation.RequestMappingHandlerMapping" />
<!-- 配置annotation类型的处理器适配器 -->
<bean class="org.springframework.web.servlet.mvc.method.annotation.RequestMappingHandlerAdapter">
    <property name="messageConverters">

            <bean class="org.springframework.http.converter.ByteArrayHttpMessageConverter" />
            <bean class="org.springframework.http.converter.BufferedImageHttpMessageConverter" />
        </list>
    </property>
</bean>
<!-- 视图解析器 -->
<bean id="viewResolver" class="org.springframework.web.servlet.view.InternalResourceViewResolver">
<property name="prefix" value="/WEB-INF/content/" />
<property name="suffix" value=".jsp" />
</bean>

<!-- 使用默认的servlet来响应静态文件 -->
<mvc:default-servlet-handler/>
<!-- 开启matrix-variables注释-->

    <!-- 设置不使用默认的消息转换器 -->
    <mvc:message-converters register-defaults="false">
        <!-- 配置 spring的转换器 -->
        <!-- <bean class="org.springframework.http.converter.xml.XmlAwareFormHttpMessageConverter" />-->
        <bean class="org.springframework.http.converter.xml.MappingJackson2XmlHttpMessageConverter" />
        <bean class="org.springframework.http.converter.StringHttpMessageConverter" />
        <bean class="org.springframework.http.converter.ByteArrayHttpMessageConverter" />
        <bean class="org.springframework.http.converter.BufferedImageHttpMessageConverter" />
        <!-- 配置fastjson中实现httpMessageConverter接口的转换器 -->
        <bean id="fastJsonHttpMessageConverter" class="com.alibaba.fastjson.support.spring.FastJsonHttpMessageConverter">
            <!-- 加入支持的媒体类型:返回contentType -->
            <property name="supportedMediaTypes">
                <list>
                    <value>text/html;charset=UTF-8</value>
                    <value>application/json;charset=UTF-8</value>
                </list>
            </property>
        </bean>
    </mvc:message-converters>  
</mvc:annotation-driven>

</beans>

 

将JSON部分替换为:

<!-- 配置annotation类型的处理器适配器 -->
<bean class="org.springframework.web.servlet.mvc.method.annotation.RequestMappingHandlerAdapter">
    <property name="messageConverters">
            <list>
                <ref bean="jsonHttpMessageConverter" />
            </list>
        </property>
</bean>

 

<bean id="jsonHttpMessageConverter" class="org.springframework.http.converter.json.MappingJackson2HttpMessageConverter">
    <property name="supportedMediaTypes">
        <list>
            <value>application/json;charset=UTF-8</value>
        </list>
    </property>
</bean>

 

问题解决!
