eclipse搭建springboot+ssm的demo

springboot:简化了ssm的xml配置,自带tomcat服务器;

什么是springboot?

 1) Spring Boot使编码变简单

 2) Spring Boot使配置变简单

 3) Spring Boot使部署变简单

 4) Spring Boot使监控变简单

SpringBoot是伴随着Spring4.0诞生的；

从字面理解，Boot是引导的意思，因此SpringBoot帮助开发者快速搭建Spring框架；

SpringBoot帮助开发者快速启动一个Web容器；

SpringBoot继承了原有Spring框架的优秀基因；

SpringBoot简化了使用Spring的过程。

Spring+SpringMVC+Mybatis开发框架ssm框架demo搭建|html|jsp

step1:java环境配置，安装jdk8，此步略。

step2:工具准备，安装java版eclipse

https://www.eclipse.org/

step3:安装 Spring Tool Suite

help->Install New Software->通过下面地址进行安装

http://download.springsource.com/release/TOOLS/update/e4.9/
step4:重启eclipse

多了如上图标，这表示工具安装成功。

step5:手动创建springboot项目

New->Project->Spring Boot->Spring Starter Project

step6:项目名称

step7:根据你项目具体情况进行选择，这里选择Web+Mysql+DevTools+MyBatis+Thymeleaf

目录及文件创建情况：

step8:文件源码：

DolearnApplication.java:自动创建

StringUtil.java

package com.example.demo.common;
 
public class StringUtil {
	public static boolean isNullOrZero (String str) {
		if(str == null || str.trim().length() == 0) {
			return true;
		}
		return false;
	}
}

controller层： LoginController.java

package com.example.demo.controller;
 
import org.mybatis.spring.annotation.MapperScan;
import org.springframework.beans.factory.annotation.Autowired;
import org.springframework.stereotype.Controller;
import org.springframework.web.bind.annotation.RequestMapping;
import org.springframework.web.bind.annotation.RequestMethod;
 
import com.example.demo.entity.Member;
import com.example.demo.service.IMember;
 
@Controller 
@MapperScan("com.example.demo.dao") //mapper扫描
public class LoginController{
 
	@Autowired
	IMember iMemberFunc;
	@RequestMapping(value = "/hello")
	public String hello(){
		System.out.println("Hello");
		return "Log";
	}
 
	@RequestMapping(value = "/login",method = RequestMethod.GET)
    public String addUser1(String name,String password) {
        System.out.println("loginName is:"+name);
        System.out.println("loginPassword is:"+password);
        try {
			Member member = iMemberFunc.login(name, password);
			if(member == null){
				System.out.println("登录失败");
				return "Log_fail";
			}else {
				System.out.println("登录成功");
				return "Log_success";
			}
		} catch (Exception e) {
			// TODO Auto-generated catch block
			e.printStackTrace();
			System.out.println(e.getMessage());
			System.out.println("登录异常");
		}
		return null;
        
	}
 
}

dao层： MemberDao.java

MemberDao.java

package com.example.demo.dao;
 
import org.apache.ibatis.annotations.Mapper;
import org.apache.ibatis.annotations.Param;
import com.example.demo.entity.Member;
import org.apache.ibatis.annotations.Select;
 
//@Mapper    
public interface MemberDao {
    @Select("select * from Member where name = #{name}")
	Member selectMemberByName(@Param("name")String name)throws Exception;
}

实体类： Member.java

Member.java

package com.example.demo.entity;
 
public class Member {
	private int id;
	private String name;
	private String password;
	public Member(){}
	public Member(int id, String name, String password) {
		super();
		this.id = id;
		this.name = name;
		this.password = password;
	}
	public int getId() {
		return id;
	}
	public void setId(int 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;
	}
	@Override
	public String toString() {
		return "Member [id=" + id + ", name=" + name + ", password=" + password
				+ "]";
	}
	
}

service接口层： IMember.java

IMember.java

package com.example.demo.service;
 
import com.example.demo.entity.Member;
 
public interface IMember {
	Member login(String name, String passsword) throws Exception;
}

service接口实现层： IMemberImpl.java

MemberImpl.java

package com.example.demo.service;
 
import com.example.demo.service.IMember;
import org.springframework.beans.factory.annotation.Autowired;
import org.springframework.stereotype.Service;
import com.example.demo.common.StringUtil;
import com.example.demo.entity.Member;
import com.example.demo.dao.MemberDao;
 
@Service
public class MemberImpl implements IMember {
		@Autowired
		private MemberDao mDao;
 
		public Member login(String name, String password) throws Exception {
		// System.out.println(name + password);
		if (StringUtil.isNullOrZero(name)) {
			System.out.println("登录名不能为空");
			return null;
		}
		if (StringUtil.isNullOrZero(password)) {
			System.out.println("密码不能为空");
			return null;
		}
		Member member = mDao.selectMemberByName(name);
		if (member == null)
			System.out.println("登录名错误");
		if (member != null&&member.getName().equals(name)&&!password.equals(member.getPassword())) {
			System.out.println("密码错误");	
		return null;
		}
		return member;
	}
 
}
