Spring 引导编码/特殊字符

Question

我对 Spring 引导 REST API 特殊 cs_CS 字符的编码有问题。

示例：

@ResponseBody
@RequestMapping("/api/test")
public String test(){
    String specialCH = "ěščřžýáíéúů";
    System.out.println(specialCH);

    return specialCH;
}

ěščřžýáíéúů

浏览器结果：

result

application.properties:

server.servlet.encoding.charset=UTF-8
server.servlet.encoding.force=true

OS Windows 10 1909.

PS: 如果我创建文件 test.html ->

+ěššččřřžýáíéáý

浏览器结果：

我找到了解决方案

只需要在 Spring MVC 返回字符串中强制使用 UTF-8 编码：

在@RequestMapping中，使用：

produces = MediaType.APPLICATION_JSON_VALUE + "; charset=utf-8"
