Question

我在jsp上显示UTF-8字符时遇到问题。

我在eclipse中使用eclipse，jsp文件，java类和tomcat 7 buit。我有3个文件：

 - index.jsp

    <%@ page language="java" contentType="text/html; charset=UTF-8"%>
    <!DOCTYPE html PUBLIC "-//W3C//DTD HTML 4.01 Transitional//EN" "http://www.w3.org/TR/html4/loose.dtd">
    <html>
    <head>
    <meta http-equiv="Content-Type" content="text/html; charset=UTF-8">
    <title>Insert title here</title>
    </head>
    <body>
        <form action="getProperties.jsp" method="post" name="GettingMovieParameters">
        Choose your name : <input type="text" name="hebrewMovieName"> 
        <input type="submit" value="send">
        </form>
    </body>
    </html>

getProperties.jsp

<jsp:useBean id="propertiesBean" class="my.movieDownloader.org.UserData" scope="session"/>
<jsp:setProperty name="propertiesBean" property="*"/> 

<html>
<head>
<meta http-equiv="Content-Type" content="text/html; charset=UTF-8">
<title>Insert title here</title>
</head>
<body>
    Movie hebrew name is : <%= propertiesBean.getHebrewMovieName() %>
</body>
</html>



  UserData.java

    public class UserData {
    private String hebrewMovieName;

    public String getHebrewMovieName() {
        return hebrewMovieName;
    }
    public void setHebrewMovieName(String hebrewMovieName) {
        System.out.println("Setting up: "  +hebrewMovieName);
        this.hebrewMovieName = hebrewMovieName;
    }
}

我试图在eclipse编辑器，jsp文件，html文件等中设置UTF-8编码。什么都行不通。我不知道我错过了什么，但如果有人可以帮助我，我会很高兴。谢谢，或

服务器端

过滤器可能是解决方案，我使用了Spring的CharacterEncodingFilter：

  <filter>
    <filter-name>CharacterEncodingFilter</filter-name>
    <filter-class>org.springframework.web.filter.CharacterEncodingFilter</filter-class>
    <init-param>
      <param-name>encoding</param-name>
      <param-value>UTF-8</param-value>
    </init-param>
    <init-param>
      <param-name>forceEncoding</param-name>
      <param-value>true</param-value>
    </init-param>
  </filter>
  ...
  <filter-mapping>
    <filter-name>CharacterEncodingFilter</filter-name>
    <url-pattern>/*</url-pattern>
  </filter-mapping>

客户端

如果您在显示或发送字符时遇到问题，请尝试使用jsp页面指令设置页面编码：

<jsp:directive.page contentType="text/html;charset=UTF-8"/>

（应替换＆lt;％@ page＆gt;和＆lt; meta＆gt;标记）

您似乎需要配置webapp以正确设置传入发布数据的字符编码。不幸的是，默认值是ISO-8859-1，tomcat坚持规范中的默认设置。您需要手动将其设置为UTF-8。这在这里解释：

http://wiki.apache.org/tomcat/FAQ/CharacterEncoding#Q3

简短版本：将其添加到web.xml应该会有所帮助：

<filter>
    <filter-name>CharacterEncodingFilter</filter-name>
    <filter-class>org.apache.catalina.filters.SetCharacterEncodingFilter</filter-class>
    <init-param>
        <param-name>encoding</param-name>
        <param-value>UTF-8</param-value>
    </init-param>
</filter>
<filter-mapping>
    <filter-name>CharacterEncodingFilter</filter-name>
    <url-pattern>/*</url-pattern>
</filter-mapping>
