分析

查看http://localhost:8090/modeler/editor/stencilset?version=1613884245370请求，响应内容
"{\r\n  \"title\": \"流程编辑器\",\r\n  \"namespace\": \"http://b3mn.org/stencilset/bpmn2.0#\",\r\n  \"description\": \"BPMN流程编辑器\",\r\n  \"propertyPackages\": 。。。
发现返回的是字符串，实际需要返回的是json字符串，继续看后台，发现使用了MappingJackson2HttpMessageConverter

     //定义时间格式转换器
     @Bean
     public MappingJackson2HttpMessageConverter jackson2HttpMessageConverter() {
         MappingJackson2HttpMessageConverter converter = new MappingJackson2HttpMessageConverter();
         ObjectMapper mapper = new ObjectMapper();
         mapper.configure(DeserializationFeature.FAIL_ON_UNKNOWN_PROPERTIES, false);
         mapper.setDateFormat(new SimpleDateFormat("yyyy-MM-dd HH:mm:ss"));
         converter.setObjectMapper(mapper);
         return converter;
     }

       //添加转换器
     @Override
     protected void configureMessageConverters(List> converters) {
       super.configureMessageConverters(converters);
       //将我们定义的时间格式转换器添加到转换器列表中,
         //这样jackson格式化时候但凡遇到Date类型就会转换成我们定义的格式
         converters.add(jackson2HttpMessageConverter());
     }

将代码注释掉，不要使用MappingJackson2HttpMessageConverter就正常了
