代码如下

mockMvc                 .perform(MockMvcRequestBuilders                         .post("/mock/post")                         .content(JSON.toJSONString(person1))                         .contentType(MediaType.APPLICATION_JSON)                         .header("X-Access-token", "1"))                 .andExpect(MockMvcResultMatchers.status().isOk())                 .andDo(MockMvcResultHandlers.print())                 .andReturn().getResponse().setCharacterEncoding("UTF-8");

设置了 utf-8 了，idea 控制台打印结果

MockHttpServletResponse:            Status = 200     Error message = null           Headers = [Content-Type:"application/json"]      Content type = application/json              Body = {"code":200,"result":"åè®¸è¿å¥"}     Forwarded URL = null    Redirected URL = null           Cookies = []

使用 HTTP-CLIENT 返回正常

HTTP/1.1 200  Content-Type: application/json Transfer-Encoding: chunked Date: Wed, 03 Feb 2021 03:13:42 GMT Keep-Alive: timeout=60 Connection: keep-alive  {   "code": 200,   "result": "允许进入" }

不知道怎么办了。。求助

我是直接参考 MockMvcResultHandlers.PrintWriterPrintingResultHandler 写了一个直接指定 Charset 的 PrintingResultHandler 子类然后在测试里用，而不用 MockMvcResultHandlers.print()…

不过 MockHttpServletRequest 和 MockHttpServletResponse 设置 CharacterEncoding 的时候会更新 ContentType…
所以如果有调用 andExpect 对比 ContentType 的话，比如

andExpect(content().contentType(MediaType.APPLICATION_JSON))

得放在 andDo 前面…
