关于SPRING MVC 的错误

在构建SPRING3.2 MVC 中出现的问题

[code="java"]

    <property name="mediaTypes">
        <map>
            <entry key="html" value="text/html" />
            <entry key="pdf" value="application/pdf" />
            <entry key="xsl" value="application/vnd.ms-excel" />
            <entry key="xml" value="application/xml" />
            <entry key="json" value="application/json" />
        </map>
    </property>

[/code]

我一加上上面的这个东西我的项目在访问的时候报错错误信息是

[code="java"]

java.lang.ClassCastException: java.lang.String cannot be cast to org.springframework.http.MediaType

spring3.2的bug

ContentNegotiatingViewResolver
public void setMediaTypes(Map mediaTypes)
{
if (mediaTypes != null)
this.cnManagerFactoryBean.getMediaTypes().putAll(mediaTypes);
}

与

MappingMediaTypeFileExtensionResolver构造器：
public MappingMediaTypeFileExtensionResolver(Map mediaTypes)
{
if (mediaTypes != null)
for (Map.Entry entries : mediaTypes.entrySet()) {
String extension = ((String)entries.getKey()).toLowerCase(Locale.ENGLISH);
MediaType mediaType = (MediaType)entries.getValue();
addMapping(extension, mediaType);
}
}

Map的value是不兼容的。

而且spring3.2开始不推荐使用setMediaTypes等直接设置这些数据，而是通过ContentNegotiationManager（ContentNegotiationManagerFactoryBean）

如

注入即可
