Question

我从命令提示符下部署了我的spring boot项目。它成功创建了WAR文件，但是当我尝试使用命令“ Catalina.bat run”运行它时，我只看到tomcat服务器在端口上打开，而我却无法执行CRUD操作，而我的代码在部署之前运行良好。因此，请对此提出一些解决方案。预先谢谢你。

Main.java

package jdbc_conn;

import org.springframework.boot.SpringApplication;
import org.springframework.boot.autoconfigure.SpringBootApplication;

@SpringBootApplication
public class JdbcConnection
{

    public static void main(String[] args)
    {
        SpringApplication.run(JdbcConnection.class, args);

    }


}

Controller.java

package jdbc_conn;

import org.springframework.beans.factory.annotation.Autowired;
import org.springframework.jdbc.core.JdbcTemplate;
import org.springframework.web.bind.annotation.RequestMapping;
import org.springframework.web.bind.annotation.RestController;

@RestController
public class JdbcOperation {
    @Autowired
    JdbcTemplate jdbc;

    @RequestMapping("/insert")
    public String insert() {
        jdbc.execute("insert into student( Name, Contact) values ('Sanket','7588832088')");
        return "data Inserted Successfully";

    }

    @RequestMapping("/delete")
    public String Delete() {
        jdbc.execute("delete from student where Roll_No=2");
        return "Data Deleted Successfully";

    }

    @RequestMapping("/update")
    public String update() {
        jdbc.execute("update  student set Name='Santosh' where Roll_no=1");
        return "Data Update Successfully";

    }
}
