运行验证测试并将这些讨厌的字符嵌入到 Swagger 2.0 验证输出中
{"$ref":"#/definitions/DeferredResult«ResponseEntity«SummCollection»»"
控制器方法返回：DeferredResult<ResponseEntity<SummCollection>>
我只是在写问题时注意到：实际：“<”疯狂：“«”
MockHttpServletRequest Swagger2 DeferredResult  响应中的奇怪字符
这似乎是“iso-8859-1”与“utf-8”之间的问题，对吧？身份证。
问题是什么导致 SwaggerTest validateImplementationAgainstDesignSpec 读取文件 .yaml json 就好了，但是 MockMvc 执行 GET 响应是在类名和分隔符之间包含这些“”字符。
代码调用：
MvcResult mvcResult = this.mockMvc.perform(get("/v2/api-docs?group=full-api") // 2
.accept(MediaType.APPLICATION_JSON)
.characterEncoding("application/json;charset=ISO-8859-1"))
.andDo(MockMvcResultHandlers.print())
.andExpect(status().isOk())
.andReturn();
我已经将代码.characterEncoding("application/json;charset=ISO-8859-1"))设置为“UTF-8”以及其他所有极端情况（包括“windows-1252”）。这发生在 Linux CI 服务器上，所以它不是一个绕口令。
我已经读过它是一个StringHttpMessageConverter问题/症状，但无济于事如何解决使用 MockMVC 调用 Swagger2 的问题。
