java web开发入门八（ssm整合）基于intellig idea

ssm整合

一、导入相关包

二、开发流程

1.写entity

package com.eggtwo.euq.entity;


import java.io.Serializable;
import java.math.BigDecimal;
import java.util.Date;

public class Member {
    private int id;

    public int getId() {
        return id;
    }

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

    private String name;
    private int age;
    private Date birthday;
    private boolean man;
    private BigDecimal score;

    public BigDecimal getScore() {
        return score;
    }

    public void setScore(BigDecimal score) {
        this.score = score;
    }

    public String getName() {
        return name;
    }

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

    public int getAge() {
        return age;
    }

    public void setAge(int age) {
        this.age = age;
    }

    public Date getBirthday() {
        return birthday;
    }

    public void setBirthday(Date birthday) {
        this.birthday = birthday;
    }

    public boolean isMan() {
        return man;
    }

    public void setMan(boolean man) {
        this.man = man;
    }

    @Override
    public String toString() {
        return "Member{" +
                "id=" + id +
                ", name='" + name + '\'' +
                ", age=" + age +
                ", birthday=" + birthday +
                ", man=" + man +
                ", score=" + score +
                '}';
    }
}

2.配mapper.xml

<?xml version="1.0" encoding="UTF-8" ?>
DOCTYPE mapper

3.配mybatis.xml

<?xml version="1.0" encoding="UTF-8" ?>
DOCTYPE configuration PUBLIC "-//mybatis.org//DTD Config 3.0//EN"
        "http://mybatis.org/dtd/mybatis-3-config.dtd">
<configuration>
    
    <typeAliases>     
        
        <package name="com.eggtwo.euq.entity"/>
    typeAliases>

    
configuration>

4.编写dao

package com.eggtwo.euq.dao;

import com.eggtwo.euq.entity.Member;

public interface MemberDao {
    public void  add(Member member);
}

4.1编写service

package com.eggtwo.euq.service;

import com.eggtwo.euq.dao.MemberDao;
import com.eggtwo.euq.entity.Member;
import org.springframework.beans.factory.annotation.Autowired;
import org.springframework.stereotype.Service;

import javax.annotation.Resource;

//用注解实现IOC
@Service("memberService")
public class MemberService {

    @Autowired
    private MemberDao memberDao;

    public void add(Member member) throws Exception {
        memberDao.add(member);
       // int a = 3 / 0;

    }
}

5.配置spring.xml

<?xml version="1.0" encoding="UTF-8"?>

import org.springframework.web.bind.annotation.RequestMapping;
import org.springframework.web.bind.annotation.RequestMethod;

import java.math.BigDecimal;
import java.util.Date;

@Controller
@RequestMapping("member")
public class MemberController extends BaseController {
    @Autowired
    private MemberService memberService;
    @RequestMapping(value = "add", method = RequestMethod.GET)
    public String add(Model model)  {

        try{
            Member member = new Member();
            member.setName("旺旺");
            member.setScore(new BigDecimal(12));
            member.setMan(new Boolean(true));
            member.setBirthday(new Date());
            member.setAge(14);

        }catch (Exception e){
            e.printStackTrace();

        return "member/add";


    }
}
