Question

I can not make request encoding to work correctly. For encoding to work, i added filter to spring security:

@Bean
public CharacterEncodingFilter characterEncodingFilter() {
    CharacterEncodingFilter filter = new CharacterEncodingFilter();
    filter.setEncoding("UTF-8");
    filter.setForceEncoding(true);
    return filter;
}
@Override
protected void configure(HttpSecurity http) throws Exception {
    http.addFilterBefore(characterEncodingFilter(), CsrfFilter.class);
...
}

Add meta to my pages:

<html xmlns="http://www.w3.org/1999/xhtml">
<head>
    <meta charset="utf-8" />
...

Add UriEnconding to tomcat 8:

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

But it is not responding to none of them. When i send a request and debug it, the result is wrong. For example when i send بای as a part of request form, i recieve Ø¨Ø§Û as result. Is there any part of config i am missing?

When sending payload ajax request (with rest client and ofcource to another method) it workes correctly, but no luck with form data. My controller looks like this:

@RequestMapping(value = "/test1")
@ResponseBody
public String test1(@RequestBody String req) {
    return req;
}

@RequestMapping(value = "/test2")
@ResponseBody
public String test2(@RequestParam("search") String req) {
    return req;
}

different tries:

for test1 with Content-Type=application/json it correctly recieves the parameter.
for test2 with Content-Type=application/x-www-form-urlencoded and get method, again everything works great.
for test2 with Content-Type=application/x-www-form-urlencoded and POST method, it returns wrong encoded values.

It seems the problem is with POST method only. any suggestions?

在深入挖掘大量过滤器链并在其中移动字符编码后，终于发现了问题。另一个过滤器是在字符编码开始之前改变编码。

我只是从spring security手中获取过滤器并手动添加它作为bean来为我做过滤：

@Bean
public FilterRegistrationBean filterRegistrationBean() {
    FilterRegistrationBean registrationBean = new FilterRegistrationBean();
    CharacterEncodingFilter characterEncodingFilter = new CharacterEncodingFilter();
    characterEncodingFilter.setEncoding("UTF-8");
    registrationBean.setFilter(characterEncodingFilter);
    return registrationBean;
}

2天或搜索和尝试，只是一个简单的答案。找到答案很难的方法

如果您使用的是1.8+的spring boot，则根本不需要CharacterEncoding。它默认情况下处于完美位置，字符编码等于utf8。所以下次，只要设置属性，如果有的话！ the properties to set are：

# HTTP encoding (HttpEncodingProperties)
spring.http.encoding.charset=UTF-8 # the encoding of HTTP requests/responses
spring.http.encoding.enabled=true # enable http encoding support
spring.http.encoding.force=true # force the configured encoding

从Tomcat wiki开始：在Tomcat 8从8.0.0开始（8.0.0-RC3，具体而言），元素的URIEncoding属性的默认值取决于“strict servlet合规性“设置。 URIEncoding的默认值（严格合规关闭）现在为UTF-8。如果启用了“严格servlet遵从性”，则默认值为ISO-8859-1。

所以一般说来，没有必要在Tomcat Config中设置UriEncoding。
