我被困很久了。任何帮助将不胜感激。

从日志中我可以看到正在部署的战争名称App。尝试使用此网址：
http://localhost:8080/App/ws/req
Or
http://localhost:8080/<deployed tomcat war name>/ws/req
答案 1 :(得分：0)
TestBean readBookmarks() {
TestBean bean = new TestBean("Test", 25);
return bean;
这个函数似乎缺少@ResponseBody，TestBean（可能是一个自定义类）也不是Spring可序列化的东西。你可以尝试发送String而不是TestBean - 这应该可行。
此外，部署目录可能与您的web.xml配置（即除App之外的其他内容）不同。您可以尝试加载http://localhost:8080/ {Dir} / ws / req，其中Dir ==部署目录（！='App'）。
上述两件事应该可以解决您的问题。
