java - spring Autowiring 依赖项注入(inject)失败

转载作者：行者123 更新时间：2023-11-30 07:35:37

我一直在 Java 7(确切版本:jdk1.7.0_60)上运行我的项目，但由于公司范围内的政策更改为升级到 Java 8(版本:jdk1.8.0_73)，我已经升级了本地计算机的 JVM到jdk1.8.0_73并在此版本上配置我的项目。

以下是我的项目的事实:
Spring框架版本: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过，直到我使用 Java 7 版本，当我将其切换到 Java 8 时，我才看到这个异常。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。

谁能帮我解决这个问题吗？

最佳答案

尝试 value="java.nio.charset.StandardCharsets.UTF_8" 而不是 value="#{T(java.nio.charset.Charset).forName('UTF- 8')}"。您还需要命名您的参数，否则 Spring 将无法实例化 MediaType，因为存在多个具有 3 个参数的构造函数。

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>
