spring /spring:如何设置控制器方法的uriencoding

Question

我在tomcat 7中运行了一个spring应用程序。在这里，我有一个spring生成的控制器方法，用于调试问题：

@RequestMapping(params = "find=ByFirstNameEqualsAndLastNameEquals", method = RequestMethod.GET)
public String findAuthorsByFirstNameEqualsAndLastNameEquals(
        @RequestParam("firstName") String firstName,
        @RequestParam("lastName") String lastName,
        @RequestParam(value = "page", required = false) Integer page,
        @RequestParam(value = "size", required = false) Integer size,
        @RequestParam(value = "sortFieldName", required = false) String sortFieldName,
        @RequestParam(value = "sortOrder", required = false) String sortOrder,
        Model uiModel
        ) {

    System.out.println("find author lastname: " + lastName);
    String lastNameUTF8 = null;
    String firstNameUTF8 = null;
    try {
        lastNameUTF8 = new String(lastName.getBytes("ISO-8859-1"), "UTF-8");
        System.out.println("lastnameUTF8: " + lastNameUTF8);
        firstNameUTF8 = new String(firstName.getBytes("ISO-8859-1"),
                "UTF-8");
        System.out.println("lastnameISOtoUTF8: " + firstNameUTF8);
    } catch (UnsupportedEncodingException e) {
        // TODO Auto-generated catch block
        e.printStackTrace();
    }
            ...

正如人们在日志中看到的那样：

  find author lastname: ШÑ<U+0082>Ñ<U+0080>ембеÑ<U+0080>г
  lastnameISOtoUTF8: Штремберг

请求参数firstName和lastName编码为ISO8859-1，但我希望它们编码为UTF-8。我想我看到了大多数类似的问题

• Spring MVC URIEncoding can't send requestparam correctly
• Spring/Rest @PathVariable character encoding
• Query String is decoded by Spring Framework
• How does URIEncoding = 'UTF-8' work?
• ..。

并确保将所有的庆祝活动都设置为UTF-8：

web.xml：

<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>

tomcats server.xml：

...
<Connector port="8080" protocol="HTTP/1.1"
           connectionTimeout="20000"
           redirectPort="8443" 
          URIEncoding="UTF-8"
...
<!-- Define an AJP 1.3 Connector on port 8009 -->
 <Connector port="8009" protocol="AJP/1.3" redirectPort="8443" 
   URIEncoder="UTF-8"
/>

java论点：

/usr/local/jdk7/bin/java -Duser.language=en -Duser.country=US -Dfile.encoding=UTF-8 /usr/local/tomcatODM_TEST/bin/bootstrap.jar:/usr/local/tomcatODM_TEST/bin/tomcat ...  org.apache.catalina.startup.Bootstrap start

此外，浏览器编码设置为UTF-8，服务器和客户端上的系统LANG：

$ echo $LANG  en_US.utf8

我不知道该怎么做才能摆脱spring有趣的ISO-8859-1解码，我想.有什么想法吗？我在看什么？

Answer 1

我也有过同样的问题，在经过大量的研究后，我意识到问题在于Tomcat连接器。我尝试了所有的方法，但只在"server.xml“中添加了以下修复方法

<Connector connectionTimeout="20000" port="8080" protocol="HTTP/1.1" redirectPort="8443" URIEncoding="UTF-8"/>

很烦人的是，您不能在Spring中设置一些东西来设置URIEncoding。

而且，最初的<connector ... URIEncoding="UTF-8"/>更新不起作用，但这是因为我的Tomcat "server.xml“被夸大了，所以要确保不是这样的。
