瓷砖编码问题

发布于 2024-08-23 19:01:58 字数 1075 浏览 5 评论 0原文

我正在尝试对正在开发的 Spring 应用程序使用 UTF-8 编码，但在从图块插入属性时无法获得正确的编码。

我的 JSP 模板中有这个片段：

<head>
    <meta http-equiv="Content-Type" content="text/html; charset=utf-8"/> 
    <title><tiles:getAsString name="title" /></title>   
</head>
<body>
    <tiles:insertAttribute name="header" ignore="true" />
....

在我的tile XML 配置文件中，我有类似的内容：

<?xml version="1.0" encoding="UTF-8" ?>
<!DOCTYPE tiles-definitions PUBLIC
   "-//Apache Software Foundation//DTD Tiles Configuration 2.1//EN"
   "http://tiles.apache.org/dtds/tiles-config_2_1.dtd">
<tiles-definitions>
   <definition name="tiles:base" template="/WEB-INF/views/templates/main.jsp">
     <put-attribute name="title" value="Título" />
...

我在 eclipse 中检查了该文件是否具有 UTF-8 编码。尽管 JSP 的其余部分是正确的（例如插入标题中的 JSP 片段），但标题属性中传递的单词在页面中未正确显示（重音字符以错误的方式显示）。如果我将编码更改为 ISO-8859-1，标题就可以，但页面的其余部分是错误的。我似乎无法将图块文件中的编码更改为 UTF-8。我还在我创建的文件中查找了“ISO-8859-1”，但没有在任何文件中设置此配置。

谁能告诉我如何为图块设置正确的编码？

谢谢

I'm trying to use UTF-8 encoding for the Spring application I'm developing but I have problems in getting the correct encoding when inserting attributes from tiles.

I have this fragment in my JSP template:

<head>
    <meta http-equiv="Content-Type" content="text/html; charset=utf-8"/> 
    <title><tiles:getAsString name="title" /></title>   
</head>
<body>
    <tiles:insertAttribute name="header" ignore="true" />
....

and in my tiles XML config file I have something like:

<?xml version="1.0" encoding="UTF-8" ?>
<!DOCTYPE tiles-definitions PUBLIC
   "-//Apache Software Foundation//DTD Tiles Configuration 2.1//EN"
   "http://tiles.apache.org/dtds/tiles-config_2_1.dtd">
<tiles-definitions>
   <definition name="tiles:base" template="/WEB-INF/views/templates/main.jsp">
     <put-attribute name="title" value="Título" />
...

I have check in eclipse that this files have UTF-8 encoding.
The word passed in title attribute is not shown correctly (the accented characters are shown in a wrong way) in the page though the rest of the JSP is correct (for instance the JSP fragment which is inserted in header). If I change the encoding to ISO-8859-1 the title is OK, but the rest odf the page is wrong. It seems I cannot get to change the encoding to UTF-8 in my tiles file. I have also looked for "ISO-8859-1" in the files I've created and I haven't set up this configuration in any file.

Can anyone tell me how can I set up the correct encoding for tiles?

Thanks

将以下内容添加到 web.xml 中。这与在每个 JSP 文件中添加标头具有相同的效果。

网络.xml：

<web-app>
    ...
    <jsp-config>
        <jsp-property-group>
            <url-pattern>*.jsp</url-pattern>
            <page-encoding>UTF-8</page-encoding>
            <trim-directive-whitespaces>true</trim-directive-whitespaces>
        </jsp-property-group>
    </jsp-config>    
</web-app>

Add the following to web.xml. This has the same effect as adding the header in each JSP file.

web.xml:

<web-app>
    ...
    <jsp-config>
        <jsp-property-group>
            <url-pattern>*.jsp</url-pattern>
            <page-encoding>UTF-8</page-encoding>
            <trim-directive-whitespaces>true</trim-directive-whitespaces>
        </jsp-property-group>
    </jsp-config>    
</web-app>

这是字符集的问题，而不是编码的问题。我必须

<%@ page contentType="text/html; charset=utf-8"%>

在每个 JSP 中进行设置并且它有效。我不知道是否有更简单的方法在 Spring Web 应用程序的所有 JSP 中配置它。

It was a problem with the charset, not with the encoding. I had to set

<%@ page contentType="text/html; charset=utf-8"%>

in every JSP and it worked. I don't know if there is an easier way of configure this in all the JSPs of a Spring Web application.

另一种方法是使用 ReloadableResourceBundleMessageSource（带有属性 defaultEncoding="UTF-8"）也用于从图块插入的内容。

我的意思是您可以从tiles传递一个关键字，并使用它从资源包中输出所需的内容，如下所示：

<tiles:useAttribute id="title_key" name="title"/>
<spring:message code="${title_key}"/>

Another way could be a usage of ReloadableResourceBundleMessageSource (with property defaultEncoding="UTF-8") also for the content being inserted from tiles.

I meant you can pass a keyword from tiles, and use it to output needed content from resource bundle, like this:

<tiles:useAttribute id="title_key" name="title"/>
<spring:message code="${title_key}"/>

在我的 Struts 2.3 到 2.5 迁移过程中，我遇到了类似的问题：
JSP 引用的所有 javascript .JS 文件的内容类型（在响应标头中）现在为“application/javascript;charset=ISO-8859-1”（struts 2.5）而不是 charset=UTF-8（在 struts 2.3 中）。
对于引用 js 文件的 JSP 和脚本标记，字符集属性设置为 utf-8。

我添加了 Leonel 的代码，它终于起作用了：
但编码现在是“text/html;charset=UTF-8”。所以我丢失了应用程序/javascript。它不能正常工作。

<web-app>
...
<jsp-config>
    <jsp-property-group>
        <url-pattern>*.js</url-pattern>
        <page-encoding>UTF-8</page-encoding>
        <trim-directive-whitespaces>true</trim-directive-whitespaces>
    </jsp-property-group>
</jsp-config>

所以我尝试了其他方法：
https://www.baeldung.com/tomcat-utf-8
这样我就得到了正确的字符集和内容类型。

让我们定义一个名为 CharacterSetFilter 的类：

public class CharacterSetFilter implements Filter {

// ...

public void doFilter(
  ServletRequest request, 
  ServletResponse response, 
  FilterChain next) throws IOException, ServletException {
    request.setCharacterEncoding("UTF-8");
    response.setContentType("text/html; charset=UTF-8");
    response.setCharacterEncoding("UTF-8");
    next.doFilter(request, response);
}

// ...
}

我们需要将过滤器添加到应用程序的 web.xml 中，以便将其应用于所有请求和响应：

<filter>
 <filter-name>CharacterSetFilter</filter-name>
 <filter-class>com.baeldung.CharacterSetFilter</filter-class>
</filter>

<filter-mapping>
 <filter-name>CharacterSetFilter</filter-name>
 <url-pattern>/*</url-pattern>
</filter-mapping>

During my Struts 2.3 to 2.5 migration i encountered a similar problem :
content-type (in response header) of all javascript .JS files referenced by JSP were now "application/javascript;charset=ISO-8859-1" (struts 2.5) instead of charset=UTF-8 (in struts 2.3).
Charset attribute was set to utf-8 for JSP and script markup referencing the js file.

I added the code from Leonel and it finally worked:
but encoding is now "text/html;charset=UTF-8". So i've lost the application/javascript. it did'nt work properly.

<web-app>
...
<jsp-config>
    <jsp-property-group>
        <url-pattern>*.js</url-pattern>
        <page-encoding>UTF-8</page-encoding>
        <trim-directive-whitespaces>true</trim-directive-whitespaces>
    </jsp-property-group>
</jsp-config>

So i tried something else :
https://www.baeldung.com/tomcat-utf-8
With this i get the correct charset and content-type.

Let’s define a class named CharacterSetFilter:

public class CharacterSetFilter implements Filter {

// ...

public void doFilter(
  ServletRequest request, 
  ServletResponse response, 
  FilterChain next) throws IOException, ServletException {
    request.setCharacterEncoding("UTF-8");
    response.setContentType("text/html; charset=UTF-8");
    response.setCharacterEncoding("UTF-8");
    next.doFilter(request, response);
}

// ...
}

We need to add the filter to our application’s web.xml so that it’s applied to all requests and responses:

<filter>
 <filter-name>CharacterSetFilter</filter-name>
 <filter-class>com.baeldung.CharacterSetFilter</filter-class>
</filter>

<filter-mapping>
 <filter-name>CharacterSetFilter</filter-name>
 <url-pattern>/*</url-pattern>
</filter-mapping>
