将弹簧片发送到Spring API时遇到问题。我想发布以下JSON:
{
"username": "testümlaut",
"firstName": "test",
"lastName": "Test"
}
为此,我有一个以下方法开始:
@RequestMapping(value="/User", method=RequestMethod.POST,
produces={"application/json ; charset=utf-8"}
)
@ResponseStatus(HttpStatus.CREATED)
public @ResponseBody User postUser(@RequestBody User user) {
User user = userDao.addUser(user);
return user;
}
如你所见,我确实有一条线:
produces={"application/json ; charset=utf-8"}
但它没有帮助。我总是异常(0xfc是ü):
Failed to read HTTP message: org.springframework.http.converter.HttpMessageNotReadableException: Could not read document: Invalid UTF-8 start byte 0xfc
at [Source: java.io.PushbackInputStream@721e5ed1; line: 2, column: 19] (through reference chain: de.escosautomation.restserver.model.user.UserClone["username"]); nested exception is com.fasterxml.jackson.databind.JsonMappingException: Invalid UTF-8 start byte 0xfc
at [Source: java.io.PushbackInputStream@721e5ed1; line: 2, column: 19] (through reference chain: de.escosautomation.restserver.model.user.UserClone["username"])
我还可以添加什么才能使其正常工作?
感谢名单。

您可以在此处查看以下几个选项:
在您的应用程序服务器上进行编码。例如,在Tomcat上,在所有连接器上确保将 URIEncoding 设置为UTF-8。 E.G:
<Connector port="80" protocol="HTTP/1.1"
connectionTimeout="20000"
redirectPort="443" URIEncoding="UTF-8"/>
MediaType.APPLICATION_JSON_UTF8_VALUE
@RequestMapping(value="/User", method=RequestMethod.POST,
consumes=MediaType.APPLICATION_JSON_UTF8_VALUE,
produces=MediaType.APPLICATION_JSON_UTF8_VALUE
)
在 web.xml :
中 <filter>
<filter-name>encodingFilter</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>encodingFilter</filter-name>
<url-pattern>/*</url-pattern>
</filter-mapping>

其实我接受Yuri Yunikov的回答。
但如果有人使用SOAPui,请不要忘记在那里设置编码请求: like it is described here
