Servlet.service() for servlet [dispatcherServlet] in context with path [] threw exception...

• 控制台报错

2019-08-02 10:39:27,390 - Servlet.service() for servlet [dispatcherServlet] in context with path [] threw exception [Request processing failed; nested exception is org.thymeleaf.exceptions.TemplateInputException: Error resolving template [/part/addUser], template might not exist or might not be accessible by any of the configured Template Resolvers] with root cause
org.thymeleaf.exceptions.TemplateInputException: Error resolving template [/part/addUser], template might not exist or might not be accessible by any of the configured Template Resolvers

• postman 报错

 "message": "Error resolving template [/part/addUser], template might not exist or might not be accessible by any of the configured Template Resolvers",

• 报错背景：项目在本地正常运行，打成 jar 包之后，在服务器端，疯狂报错，就是找不到路径
• 原因：返回model的时候

	@GetMapping("/adduser")
    public ModelAndView addUser() {
        return new ModelAndView("/part/addUser");
    }

• /part/addUser，一定要吧返回视图路径的第一个/给去掉，
• 正解：

	@GetMapping("/adduser")
    public ModelAndView addUser() {
        return new ModelAndView("part/addUser");
    }
