Question

我一直在Java 7上运行我的项目（确切版本：jdk1.7.0_60），但由于公司范围的策略已更改为升级到Java 8（版本：jdk1.8.0_73），我已升级本地计算机的JVM到jdk1.8.0_73并在此版本上配置了我的项目。

以下是我项目的事实：
Spring Framework版本：4.0.3.RELEASE
Java：jdk1.8.0_73

从那时起，我的应用程序抛出以下异常：

这个问题从来没有出现，直到我使用Java 7版本，当我将其切换到Java 8然后我看到这个例外。由于此编辑器的限制，我无法粘贴整个异常日志。如果需要，将粘贴在评论中。

任何人都可以帮我解决这个问题吗？

Answer 1

尝试使用value="java.nio.charset.StandardCharsets.UTF_8"代替value="#{T(java.nio.charset.Charset).forName('UTF-8')}"。您还需要为参数命名，否则Spring将无法实例化MediaType，因为存在具有3个参数的多个构造函数。

您可以尝试以下代码：

<bean class="org.springframework.http.MediaType" >
        <constructor-arg name="type" value="application" />
        <constructor-arg  name="subtype" value="json" />
        <constructor-arg name="charset" value="#{T(java.nio.charset.StandardCharsets).UTF_8}"/>
    </bean>

感谢@ louis-f指出问题并提供解决方案。我尝试用上述建议解决这个问题，但它仍然给出相同的例外。然后我尝试了以下它解决了我的问题：

        <bean id="restTemplate" class="org.springframework.web.client.RestTemplate">
            <property name="messageConverters">
                <list>
                    <bean class="org.springframework.http.converter.json.MappingJackson2HttpMessageConverter">
                        <property name="supportedMediaTypes">
                            <list>
                                <bean class="org.springframework.http.MediaType">
                                    <constructor-arg name="type" value="application"/>
                                    <constructor-arg name="subtype" value="json"/>
                                    <constructor-arg name="charset" value="UTF-8" />
                                </bean>
                            </list>
                        </property>
                    </bean>
                    <bean class="org.springframework.http.converter.xml.SourceHttpMessageConverter"/> 
                    <bean class="org.springframework.http.converter.StringHttpMessageConverter">
                        <constructor-arg name="defaultCharset" value="UTF-8" />
                    </bean> 
                </list>
            </property>
        </bean>

所以，我实际上做的只是将charset构造函数参数更改为字符串值，即“UTF-8”，它确实对我有用。在应用程序调试中 - 我在inspect元素中检查了对象restTemplate，现在我已经为messageConverters列表正确地进行了所有操作。

再次感谢。
