springmvc+spring+mybatis框架的搭建

本篇博客参考自：https://www.cnblogs.com/lmei/p/7190755.html?utm_source=itdadao&utm_medium=referral

首先来了解一下mybatis：

        MyBatis 是一款优秀的持久层框架，它支持定制化 SQL、存储过程以及高级映射。MyBatis 避免了几乎所有的 JDBC 代码和手动设置参数以及获取结果集。MyBatis 可以使用简单的 XML 或注解来配置和映射原生信息，将接口和 Java 的 POJOs(Plain Ordinary Java Object,普通的 Java对象)映射成数据库中的记录。（来源百度百科）

首先建一个springmvc项目（建议使用STS，STS使用与eclipse一致）

STS下载

创建springmvc项目步骤

项目视图

在pom.xml复制下列jar包（这是从maven官网直接下载jar包，无需自己寻找jar包，下载需要一段时间建议到网络好的地方下载）

在src/main/java处创建包名

其次在src/main/resources处配置xml文件（注意中间的root-context.xml与servlet-context.xml文件我是从下面拉上来的）

ApplicationContext.xml（此文件里有许多包名，建议使用Ctrl+F一键替换避免遗漏）

db.properties

jdbc.driver=com.mysql.jdbc.Driver
jdbc.url=jdbc:mysql://localhost:3306/test?useUnicode=true&characterEncoding=UTF-8&zeroDateTimeBehavior=convertToNull
jdbc.username=账号
jdbc.password=密码

 

servlet-context.xml

HomeController.java

package com.zjq.ssm.controller;

import java.util.List;

import javax.annotation.Resource;

import org.springframework.beans.factory.annotation.Autowired;
import org.springframework.stereotype.Controller;
import org.springframework.ui.Model;
import org.springframework.web.bind.annotation.RequestMapping;

import com.zjq.ssm.entity.Book;
import com.zjq.ssm.service.BookService;


@Controller
@RequestMapping("/Book")
public class HomeController {
	
	@Resource
	@Autowired
	BookService bookService;

	@RequestMapping("/getAllBook")
	public String getAllBook(Model model) {
		List books = bookService.getAllBook();
		for (Book book : books) {
			System.out.println(book.getBookName());
		}
		
		model.addAttribute("books", books);
		return "success";
	}
	
}

BookDao.java

package com.zjq.ssm.dao;

import java.util.List;
import com.zjq.ssm.entity.Book;

public interface BookDao {

	public List getAllBook();
}

Book.java

package com.zjq.ssm.entity;

import java.io.Serializable;

public class Book implements Serializable {
	private static final long serialVersionUID = 1L;
	private int id;
	private String bookName;

	public int getId() {
		return id;
	}

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

	public String getBookName() {
		return bookName;
	}

	public void setBookName(String bookName) {
		this.bookName = bookName;
	}

	@Override
	public String toString() {
		return "id：" + getId() + "，bookName：" + getBookName() ;
	}

}

BookServiceImpl.java

package com.zjq.ssm.impl;

import java.util.List;
import javax.annotation.Resource;

import org.springframework.stereotype.Service;

import com.zjq.ssm.dao.BookDao;
import com.zjq.ssm.entity.Book;
import com.zjq.ssm.service.BookService;

@Service
public class BookServiceImpl implements BookService{
	@Resource
	BookDao bookDao;
	
	@Override
	public List getAllBook() {	
		return bookDao.getAllBook();
	}
}

BookMapper.xml

    
        select * from tb_book 
    

BookService.java

package com.zjq.ssm.service;

import java.util.List;
import com.zjq.ssm.entity.Book;

public interface BookService {

    public List getAllBook();
}

web.xml

	
	
		contextConfigLocation
		classpath:root-context.xml,classpath:ApplicationContext.xml
	
	
	
	
		org.springframework.web.context.ContextLoaderListener
	

	
	
		appServlet
		org.springframework.web.servlet.DispatcherServlet
		
			contextConfigLocation
			classpath:servlet-context.xml
		
		1

此处记得添加

创建数据库（id为递增）

index.jsp

<%@ page language="java" contentType="text/html; charset=UTF-8"
	pageEncoding="UTF-8"%>







	跳转

success.xml

<%@ page language="java" contentType="text/html; charset=UTF-8" pageEncoding="UTF-8"%>
<%@taglib prefix="c" uri="http://java.sun.com/jsp/jstl/core"%>
<%@taglib prefix="fmt" uri="http://java.sun.com/jsp/jstl/fmt" %>

${book.id}
