如何为我的所有 Spring 控制器异常创建一个通用页面？

Question

我正在使用 Spring 3.2.11.RELEASE。我正在尝试将 JSP 设置为来自我的控制器的任何异常的包罗万象的页面。但是，该机制没有启动。我已将其添加到我的 web.xml 文件中

<?xml version="1.0" encoding="UTF-8"?>

    </error-page>

    <welcome-file-list>
        <welcome-file>index.html</welcome-file>
    </welcome-file-list>
</web-app>

并在我的 WEB-INF 目录中创建了 error.jsp。但是，当从我的控制器中生成异常时，例如NullPointerExceptions，我没有看到 error.jsp 页面，而是一个通用的 spring 消息，上面写着“{“status”:“failure”“exception”:“NullPointerException”}。我还需要做哪些其他配置才能使用我的通用错误页面？如果这很重要，我正在使用 JBoss 7.1.3.Final。

这是应用程序上下文文件，在上面的 web.xml 文件中引用：

Answer 1

尝试像这样在您的 web.xml 中使用：

<error-page>
    <exception-type>java.lang.Exception</exception-type>
    <location>/WEB-INF/error.jsp</location>
</error-page>

你在使用 Spring MVC 吗？如果是这样，请尝试在您的 mvc 应用程序上下文中配置异常解析器，如下所示：

<bean class="org.springframework.web.servlet.handler.SimpleMappingExceptionResolver" p:order="3" p:defaultErrorView="error" />

您的 error.jsp 必须位于您的 viewResolver 的路径中（例如 "WEB-INF/pages"、"WEB-INF/views" 等）。

PS.：要使用 p:*，您必须在 bean 中添加 xmlns:p="http://www.springframework.org/schema/p"，如下所示：

<beans xmlns:xsi="http://www.w3.org/2001/XMLSchema-instance"
    xmlns="http://www.springframework.org/schema/beans" xmlns:context="http://www.springframework.org/schema/context"
    xmlns:p="http://www.springframework.org/schema/p" xmlns:mvc="http://www.springframework.org/schema/mvc"
    xsi:schemaLocation="http://www.springframework.org/schema/beans classpath:org/springframework/beans/factory/xml/spring-beans-3.2.xsd
                        http://www.springframework.org/schema/context http://www.springframework.org/schema/context/spring-context-3.2.xsd
                        http://www.springframework.org/schema/mvc http://www.springframework.org/schema/mvc/spring-mvc-3.2.xsd">

    <!-- your configs go here -->

</beans>

您还可以将 @ExceptionHandler 和/或 @ControllerAdvice 与 Spring MVC 一起使用。
