查询字符串中的字符编码,希伯来语

Question

我正在尝试使用希伯来语中的查询字符串参数发送GET请求.当控制器获得请求时,参数是乱码.我添加了"org.springframework.web.filter.CharacterEncodingFilter",但它没有改变一件事.

请告知如何解决它.

更新:这是请求.

事实证明HttpServletRequest#setCharacterEncoding(String)哪些CharacterEncodingFilter用途

覆盖此请求正文中使用的字符编码的名称.必须在读取请求参数或使用getReader()读取输入之前调用此方法.否则,它没有任何效果.

这对你没有好处,因为你没有从正文中获取参数,而是从查询字符串中获取参数.

但是,如果您使用的是Tomcat,那么您很幸运.Tomcat有一个特殊Connector属性,当设置(默认情况下未设置)时,将对查询字符串使用相同的字符编码.

那个属性是useBodyEncodingForURI.如果你打开你的Tomcat servet.xml文件,你会发现一个像(没有属性)的元素

<Connector connectionTimeout="20000" port="8080" protocol="HTTP/1.1"
    redirectPort="8443" useBodyEncodingForURI="true">
</Connector>

添加属性,它将按预期工作.Connector在这种情况下,请确保为适当的HTTP 设置它.

其他Servlet容器可能有一些类似的配置.
