Question

我有一个GlassFish 3.1.2应用服务器，我已经开始使用JSP页面，所以我有兴趣为UTF-8正确配置编码。

我的原始工作web.xml文件以

开头

<?xml version="1.0" encoding="UTF-8"?>
<!DOCTYPE web-app PUBLIC "-//Sun Microsystems, Inc.//DTD Web Application 2.3//EN" 
   "http://java.sun.com/dtd/web-app_2_3.dtd">

然后我添加了以下内容以强制使用UTF-8编码

<jsp-config>
   <jsp-property-group>
       <url-pattern>*.jsp</url-pattern>
       <page-encoding>UTF-8</page-encoding>
   </jsp-property-group> 
</jsp-config>

报告我的GlassFish 3.1.2服务器日志文件

Element type <jsp-config> must be declared web.xml

为了修复错误，我将web.xml文件的开头更改为

<?xml version="1.0" encoding="UTF-8"?>  
<web-app xmlns="http://java.sun.com/xml/ns/j2ee"
     xmlns:xsi="http://www.w3.org/2001/XMLSchema-instance"
     xsi:schemaLocation="http://java.sun.com/xml/ns/j2ee http://java.sun.com/xml/ns/j2ee/web-app_2_4.xsd"
 version="2.4" >

现在我收到了GlassFish服务器错误

Invalid Deployment Descriptors in Deployment descriptor file WEB-INF/web.xml ...
One of '{"http://java.sun.com/xml/ns/j2ee":servlet-class, 
         "http://java.sun.com/xml/ns/j2ee":jsp-file}' is expected.

我的语法是否关闭？如何让<jsp-config>使用版本2.3的xml.web文件中的标题？

如果我将web.xml文件作为

启动

<?xml version="1.0" encoding="UTF-8"?>
<web-app xmlns:xsi="http://www.w3.org/2001/XMLSchema-instance"
    xmlns="http://java.sun.com/xml/ns/javaee" xmlns:web="http://java.sun.com/xml/ns/javaee"
    xsi:schemaLocation="http://java.sun.com/xml/ns/javaee http://java.sun.com/xml/ns/javaee/web-app_2_3.xsd"
    version="2.3">

</servlet-mapping>

<jsp-config>

      <url-pattern>*.jsp</url-pattern>
      <page-encoding>UTF-8</page-encoding>
  </jsp-property-group>
</jsp-config>

</web-app>

我看到了这个错误：

或者，我在glassfish-web.xml目录中也有一个WEB-INF文件。如果我将web.xml文件还原为原始文件并将<jsp-config>部分放在glassfish-web.xml而不是web.xml中，则服务器启动正常。哪个文件<jsp-config>应该进入，或者它是否重要？

Answer 1

要使用UTF-8配置JSP，您需要在jsp的第一行使用

<%@ page language="java" contentType="text/html; charset=UTF-8" pageEncoding="UTF-8"%>

你应该使用它，但你的版本：

<?xml version="1.0" encoding="UTF-8"?>
<web-app xmlns:xsi="http://www.w3.org/2001/XMLSchema-instance"
    xmlns="http://java.sun.com/xml/ns/javaee" xmlns:web="http://java.sun.com/xml/ns/javaee"
    xsi:schemaLocation="http://java.sun.com/xml/ns/javaee http://java.sun.com/xml/ns/javaee/web-app_3_0.xsd"
    version="3.0">

我的web.xml示例

<?xml version="1.0" encoding="UTF-8"?>
<web-app xmlns:xsi="http://www.w3.org/2001/XMLSchema-instance"
    xmlns="http://java.sun.com/xml/ns/javaee" xmlns:web="http://java.sun.com/xml/ns/javaee"
    xsi:schemaLocation="http://java.sun.com/xml/ns/javaee http://java.sun.com/xml/ns/javaee/web-app_3_0.xsd"
    version="3.0">
    <display-name>base</display-name>
    <servlet>
        <servlet-name>mvc-dispatcher</servlet-name>
        <servlet-class>org.springframework.web.servlet.DispatcherServlet</servlet-class>
        <init-param>
            <param-name>contextConfigLocation</param-name>
            <param-value>
                /WEB-INF/spring/spring-mvc-dispatcher.xml
            </param-value>
        </init-param>
        <load-on-startup>1</load-on-startup>
    </servlet>
    <servlet-mapping>
        <servlet-name>mvc-dispatcher</servlet-name>
        <url-pattern>/</url-pattern>
    </servlet-mapping>
    <listener>
        <listener-class>org.springframework.web.context.ContextLoaderListener</listener-class>
    </listener>

Answer 2

对于servlet 3.1 api级别使用：

<?xml version="1.0" encoding="ISO-8859-1"?>

<web-app xmlns="http://xmlns.jcp.org/xml/ns/javaee"
  xmlns:xsi="http://www.w3.org/2001/XMLSchema-instance"
  xsi:schemaLocation="http://xmlns.jcp.org/xml/ns/javaee
                      http://xmlns.jcp.org/xml/ns/javaee/web-app_3_1.xsd"
  version="3.1"
  metadata-complete="true">

什么是标准的web.xml java头来获取<jsp-config>标签工作？</jsp-config>
