App.java

package com.eid.controller;
    import org.springframework.boot.SpringApplication;
    import org.springframework.boot.autoconfigure.EnableAutoConfiguration;
    import org.springframework.context.annotation.ComponentScan;
    
    @ComponentScan
    @EnableAutoConfiguration
    public class App {
        public static void main(String[] args) {
        	System.out.println("Start App Class....");
            SpringApplication.run(App.class, args);
        }
    }

SpringBootStartApplication.java

package com.eid.controller;
    
    import org.springframework.boot.builder.SpringApplicationBuilder;
    import org.springframework.boot.web.SpringBootServletInitializer;
    
    /**
     * 修改启动类，继承 SpringBootServletInitializer 并重写 configure 方法
     */
    public class SpringBootStartApplication extends SpringBootServletInitializer {
    
        @Override
        protected SpringApplicationBuilder configure(SpringApplicationBuilder builder) {
            // 注意这里要指向原先用main方法执行的Application启动类
            return builder.sources(App.class);
        }
    }

TestController.java

package com.eid.controller;
    import org.springframework.boot.SpringApplication;
    import org.springframework.web.bind.annotation.RequestMapping;
    import org.springframework.web.bind.annotation.RestController;
    
    @RestController
    public class TestController {
        @RequestMapping("/t1")
        public String  showPerson() {
            return "test";
        }
    }

注意：当RestController需要接收参数是需要满足两个条件

1.请求的The request’sContent-Typeheader must be set toapplication/json.

2.The JacksonJSONlibrary must be available on the application’s classpath.

所以在classpath中添加了一个jar。问题解决了。
