后台代码，仅供参考
controll层

package com.it.controll;

import com.it.entity.User;
import com.it.service.UserService;
import org.springframework.beans.factory.annotation.Autowired;
import org.springframework.stereotype.Controller;
import org.springframework.web.bind.annotation.GetMapping;
import org.springframework.web.bind.annotation.RequestMapping;
import org.springframework.web.bind.annotation.ResponseBody;

import java.util.Date;
import java.util.List;

/**
 * @Author: machi
 * @Date:2019/2/22
 */
@Controller
@RequestMapping("/user")
public class UserController {
    private UserService userService;

    public UserController(UserService userService) {
        this.userService = userService;
    }

    @GetMapping("/find-by-all")
    @ResponseBody
    public List<User> findByAll() {
       /* List<User> list = userService.findByAll();
        for (User user : list) {
            System.out.println(user.getUsername());
        }*/
        return userService.findByAll();
    }


}

mapper层

package com.it.mapper;

import com.it.entity.User;
import org.apache.ibatis.annotations.Mapper;
import org.apache.ibatis.annotations.Select;

import java.util.List;

/**
 * @Author: machi
 * @Date:2019/2/21
 */
@Mapper
public interface UserMapper{
    /**
     *
     * @return
     */

    @Select("SELECT * from user")
    public List<User> findByAll();
}

serviceImpl层

package com.it.service.impl;

import com.it.entity.User;
import com.it.mapper.UserMapper;
import com.it.service.UserService;
import org.springframework.stereotype.Service;

import java.util.List;

/**
 * @Author: machi
 * @Date:2019/2/21
 */
@Service
public class UserServiceImpl implements UserService {

    private UserMapper userMapper;

 public UserServiceImpl(UserMapper userMapper){

     this.userMapper=userMapper;
 }

    @Override
    public List<User> findByAll() {
        System.out.println(userMapper);
        return userMapper.findByAll();
    }


}

service层

package com.it.service;

import com.it.entity.User;

import java.util.List;

/**
 * @Author: machi
 * @Date:2019/2/21
 */

public interface UserService {
    /**
     *
     * @return
     */
    public List<User> findByAll();
}

实体层

package com.it.entity;


import javax.persistence.*;
import java.io.Serializable;


/**
 * @Author: machi
 * @Date:2019/2/21
 */
@Entity
@Table(name = "user")
public class User implements Serializable {

    @GeneratedValue(strategy = GenerationType.AUTO)//主键生成策略
    @Id
    private int id;
    @Column(name = "username")
    private String username;
    @Column(name = "password")
    private String password;

    public int getId() {
        return id;
    }

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

    public String getUsername() {
        return username;
    }

    public void setUsername(String username) {
        this.username = username;
    }

    public String getPassword() {
        return password;
    }

    public void setPassword(String password) {
        this.password = password;
    }
}

application.yml 文件


server:
  port: 8081
  servlet:
    context-path: /angular
spring:
  datasource:
    url: jdbc:mysql://localhost:3306/test
    driver-class-name: com.mysql.jdbc.Driver
    username: root
    password: root

静态页面一般就用nginx代理。
