springboot+maven+idea+freemarker

这几天刚接触springboot，感觉还好，只不过发布的时候总是404，命名配置好的tomcat，每一步没有问题，先打了war.exploded,然后点击插件里面的package,最后配置的tomcat，最终才知道，根本不需要配置tomcat，直接运行springboot那个就好了。 springboot+maven+idea+freemarker

遇到了很多的问题，打jar或者war包的时候需要用到

打包的结果：

package com.example.demo.bean;

public class User {
    private Integer id;
    private String name;

    public Integer getId() {
        return id;
    }

    public void setId(Integer id) {
        this.id = id;
    }


    public String getName() {
        return name;
    }

    public void setName(String name) {
        this.name = name;
    }


}

Dao:

package com.example.demo.dao;

import com.example.demo.bean.User;
import org.apache.ibatis.annotations.Mapper;
import org.apache.ibatis.annotations.Param;
import org.apache.ibatis.annotations.Select;

@Mapper
public interface UserMapper {

    @Select("select * from user where id = #{userId}")
    User findUserById(@Param("userId") Integer userId);
}

Service：

package com.example.demo.service;

import com.example.demo.bean.User;

public interface UserService {
    User getUserById(Integer id);
}
=========================================
package com.example.demo.service.impl;

import com.example.demo.bean.User;
import com.example.demo.dao.UserMapper;
import com.example.demo.service.UserService;
import org.springframework.beans.factory.annotation.Autowired;
import org.springframework.stereotype.Service;

import java.io.Serializable;

@Service
public class UserServiceimpl implements UserService, Serializable {

   @Autowired
    private UserMapper userMapper;

   public  User getUserById(Integer id){
      return  userMapper.findUserById(id);
   }
}

Controller:

package com.example.demo.controller;

import com.example.demo.bean.User;
import com.example.demo.service.UserService;
import org.springframework.beans.factory.annotation.Autowired;
import org.springframework.web.bind.annotation.RequestMapping;
import org.springframework.web.bind.annotation.RequestParam;
import org.springframework.web.bind.annotation.RestController;
import org.springframework.web.servlet.ModelAndView;

@RestController
public class TestCotroller {
    @Autowired
    UserService userService;
    @RequestMapping("/test")
    public ModelAndView test(@RequestParam(defaultValue = "1")Integer id)
    {

        //访问路径：http://localhost:8080/test
        ModelAndView modelAndView = new ModelAndView();
        User user = userService.getUserById(id);
        System.out.println(user.getId());
        modelAndView.addObject("user",user);

        modelAndView.setViewName("test");
        System.out.println("aaaaaa");
        return modelAndView;
    }
}

test.ftl:

<!DOCTYPE html>
<html lang="en">
<head>
    <meta charset="UTF-8">
    <title>Title</title>
</head>
<body>
    我是qin,我是${user.id} ,${user.name}
</body>
</html>

application.properties:

spring.datasource.url = jdbc:mysql://localhost:3306/lsq
spring.datasource.username = root
spring.datasource.password = root
spring.datasource.driverClassName = com.mysql.jdbc.Driver

#设定ftl文件路径
spring.freemarker.template-loader-path=classpath:/templates
#设定静态文件路径，js,css等
spring.mvc.static-path-pattern=/static/**

main:

package com.example.demo;

import org.mybatis.spring.annotation.MapperScan;
import org.springframework.boot.SpringApplication;
import org.springframework.boot.autoconfigure.SpringBootApplication;

@SpringBootApplication
@MapperScan("com.example.demo.dao")
public class DemoApplication {

   public static void main(String[] args) {
      SpringApplication.run(DemoApplication.class, args);
   }
}
运行结果：

http://localhost:8080/test
