在eclipse中使用Maven搭建SSM项目

在eclipse中使用Maven搭建SSM项目

在eclipse中使用Maven搭建SSM项目
一、 搭建maven

1. 安装maven
   第一步：Apache Maven官网：http://maven.apache.org/

第二步：不想下载最新版的话，可以下载旧版

第三步：选择合适的版本，我用的是3.3.9

第四步：解压zip文件

2. 配置环境
   第一步：右击我的电–>属性–>高级系统设置–>环境变量–>系统变量–>新建

第二部：再配置Path变量

跟配置java环境是一样的，最后几个一直点确定就行。 home路径要自己定一个，不能和其他重复。路径最好是拷贝，手动输入太容易出错了。
第三步：检验配置是否成功，打开命令行，输入mvn -v

成功！！！
二、 创建Maven项目

1. 新建Maven Object项目
   File–>New -->Maven project
   
   定义名称

项目结构图

2. 配置maven
Window—>Preferences—>Maven

配置Installations

配置User Settings
3. 导入pom.xml

三、 创建Java类

1. Controller类

package com.czxy.controller;

import java.util.List;

import javax.annotation.Resource;

import org.springframework.stereotype.Controller;
import org.springframework.web.bind.annotation.RequestMapping;
import org.springframework.web.bind.annotation.RestController;

import com.czxy.domain.User;
import com.czxy.service.UserService;

@RestController
@RequestMapping("/user")
public class UserController {

	
	@Resource
	private UserService userService;
	
	@RequestMapping("/findAll")
	public List findAll(){
		List list=userService.findAll();
		System.out.println(list);
		return list;
	}
}

2.Service类

package com.czxy.service;

import java.util.List; 

import javax.annotation.Resource;

import org.springframework.stereotype.Service;
import org.springframework.transaction.annotation.Transactional;

import com.czxy.dao.UserMapper;
import com.czxy.domain.User;

@Service
@Transactional
public class UserService {
	
	
	@Resource
	private UserMapper userDao;
	
	
	public List findAll(){
		List list=userDao.selectAll();
		
		System.out.println(list);
		return list;
	}

}

3. Dao类

package com.czxy.dao;

import com.czxy.domain.User;

import tk.mybatis.mapper.common.Mapper;

@org.apache.ibatis.annotations.Mapper
public interface UserMapper extends Mapper{

}

4.实体类

package com.czxy.domain;

import javax.persistence.Entity;
import javax.persistence.Id;
import javax.persistence.Table;

@Entity
@Table(name = "tb_user")
public class User {

	@Id
	private Integer id;
	private String name;
	private String password;
	private String mobile;
	private String email;
	
	//无参
	public User() {
		super();
		// TODO Auto-generated constructor stub
	}

	//有参
	public User(Integer id, String name, String password, String mobile, String email) {
		super();
		this.id = id;
		this.name = name;
		this.password = password;
		this.mobile = mobile;
		this.email = email;
	}

	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;
	}

	public String getPassword() {
		return password;
	}

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

	public String getMobile() {
		return mobile;
	}

	public void setMobile(String mobile) {
		this.mobile = mobile;
	}

	public String getEmail() {
		return email;
	}

	public void setEmail(String email) {
		this.email = email;
	}
	
	//toString
	@Override
	public String toString() {
		return "User [id=" + id + ", name=" + name + ", password=" + password + ", mobile=" + mobile + ", email="
				+ email + "]";
	}
	
}

数据库

5. 启动类
   

package com.czxy;

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

@SpringBootApplication
public class ApplicationDemo {
	
	public static void main(String[] args) {
		SpringApplication.run(ApplicationDemo.class, args);
	}

}

6.application.yaml文件

server:
  port: 8080   #端口号

spring:
  datasource:                 
    url: jdbc:mysql://127.0.0.1:3306/shop
    username: root
    password: root
    driver-class-name: com.mysql.jdbc.Driver
    type: com.alibaba.druid.pool.DruidDataSource
    druid:                  
      initial-size: 5
      min-idle: 5
      max-active: 20
      max-wait: 1000
      test-on-borrow: true
mybatis:
  mapper-locations: classpath:mapper/*.xml
  type-aliases-package: com.czxy.domain
  

7.配置tomcat

进行校验

运行启动类

浏览器访问

console控制台打印
