@_@ 写在最前

之前分享过下面这几篇：

这一篇，在这些练习的基础上，将它们整合在一起！

搭建步骤如下

一、新建maven项目，配置环境，测试是否配置成功

二、整合spring+mybatis，添加ApplicationContext.xml文件，修改pom.xml,，并连接mysql，测试是否搭建成功

三、整合springmvc，添加springmvc-servlet.xml文件，修改调整，测试是否搭建成功

附：第一，二步详细操作步骤可参考

当然下面也会附上详细的搭建过程！

项目结构一览

现在开始体验！！!

一、新建maven项目

1、新建项目，然后修改几个配置，修改完如下：

2、添加Dynamic Web Module

Apply后，查看项目结构可以看到多了个WebContent

3、将WebContent下的两个文件复制到src/main/webapp下，然后将WebContent整个删掉

4、修改Deployment Assembly，只留下下面几个

新增/src/main/webapp，步骤Add->Floder->src->main->webapp->finish

5、测试，在src/main/webapp下，新建一个index.jsp文件

pageEncoding="UTF-8"%>

修改web.xml

xmlns="http://java.sun.com/xml/ns/javaee"

xsi:schemaLocation="http://java.sun.com/xml/ns/javaee http://java.sun.com/xml/ns/javaee/web-app_3_0.xsd"

id="WebApp_ID" version="3.0">

index.jsp

运行tomcat，访问：http://localhost:8888/SSM01/，页面显示“hello”

到此，第一步骤完成！！！

二、整合Spring+MyBatis

1、修改pom.xml，加载项目需要的jar

xsi:schemaLocation="http://maven.apache.org/POM/4.0.0 http://maven.apache.org/xsd/maven-4.0.0.xsd">

2、数据库准备

新建数据表tb_book，添加测试数据

3、新建包和类

(1)添加实体类Book

package com.lmei.ssm.entity;

public class Book {

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 this.getId()+"\t"+this.getBookName();

}

}

(2)添加Dao，BookDao

package com.lmei.ssm.dao;

import java.util.List;

import com.lmei.ssm.entity.Book;

public interface BookDao {

public List getAllBook();

}

(3)添加service，BookService

package com.lmei.ssm.service;

import java.util.List;

import com.lmei.ssm.entity.Book;

public interface BookService {

public List getAllBook();

}

(4)添加impl，BookServiceImpl实现BookService

package com.lmei.ssm.impl;

import java.util.List;

import javax.annotation.Resource;

import org.springframework.stereotype.Service;

import com.lmei.ssm.dao.BookDao;

import com.lmei.ssm.entity.Book;

import com.lmei.ssm.service.BookService;

@Service

public class BookServiceImpl implements BookService{

@Resource

BookDao bookDao;

public List getAllBook() {

return bookDao.getAllBook();

}

}

(5)添加BookMapper

select * from tb_book

4、添加ApplicationContext.xm和db.propertiesl文件，并注册映射

ApplicationContext.xml

xmlns:xsi="http://www.w3.org/2001/XMLSchema-instance" xmlns:p="http://www.springframework.org/schema/p"

xmlns:aop="http://www.springframework.org/schema/aop" xmlns:context="http://www.springframework.org/schema/context"

xsi:schemaLocation="http://www.springframework.org/schema/beans

http://www.springframework.org/schema/beans/spring-beans.xsd

http://www.springframework.org/schema/context

http://www.springframework.org/schema/context/spring-context-4.3.xsd

http://www.springframework.org/schema/aop

http://www.springframework.org/schema/aop/spring-aop-4.3.xsd">

class="org.springframework.jdbc.datasource.DriverManagerDataSource">

value="classpath:com/lmei/ssm/mapper/*Mapper.xml">

db.properties

jdbc.driver=com.mysql.jdbc.Driver

jdbc.url=jdbc:mysql://localhost:3306/test?useUnicode=true&characterEncoding=UTF-8&zeroDateTimeBehavior=convertToNull

jdbc.username=root

jdbc.password=123456

5、添加测试类

TestMyBatisSpring

package com.lmei.ssm.test;

import static org.junit.Assert.assertNotNull;

import java.util.List;

import org.junit.Test;

import org.springframework.context.ApplicationContext;

import org.springframework.context.support.ClassPathXmlApplicationContext;

import com.lmei.ssm.dao.BookDao;

import com.lmei.ssm.entity.Book;

public class TestMyBatisSpring {

@Test

public void test() {

//初始化容器

ApplicationContext ctx=new ClassPathXmlApplicationContext("ApplicationContext.xml");

//获得bean

BookDao bookDao = ctx.getBean(BookDao.class);

//访问数据库

List books = bookDao.getAllBook();

for (Book book : books) {

System.out.println(book.getBookName());

}

assertNotNull(books);

}

}

Run As->JUnit Test

到此，第二步完成Spring+MyBatis+Mysql！！！

三、整合springmvc

1、修改实体类Book

package com.lmei.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() ;

}

}

2、在WEB-INF下新建一个文件夹view，然后在里面新建hello.jsp文件，用来测试springmvc是否搭建成功

路径webapp/WEB-INF/view/hello.jsp

pageEncoding="UTF-8"%>

--%>

Insert title here

${message}

3、新建一个controller，HelloWorld.java

HelloWorld.java代码：

package com.lmei.ssm.controller;

import org.springframework.stereotype.Controller;

import org.springframework.ui.Model;

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

//@Controller是为了让Spring IOC容器初始化时自动扫描到；

//@RequestMapping是为了映射请求路径

@Controller

@RequestMapping("/Hello")

public class HelloWorld {

@RequestMapping("/SayHello")

public String SayHello(Model model) {

model.addAttribute("message", "Hello Spring MVC!");

System.out.println(model.containsAttribute("message")); //是否成功赋值

return "hello";

}

}

4、添加springmvc-servlet.xml

xmlns:xsi="http://www.w3.org/2001/XMLSchema-instance"

xmlns:context="http://www.springframework.org/schema/context"

xmlns:mvc="http://www.springframework.org/schema/mvc"

xsi:schemaLocation="http://www.springframework.org/schema/beans

http://www.springframework.org/schema/beans/spring-beans.xsd

http://www.springframework.org/schema/context

http://www.springframework.org/schema/context/spring-context-4.3.xsd

http://www.springframework.org/schema/mvc

http://www.springframework.org/schema/mvc/spring-mvc-4.3.xsd">

class="org.springframework.web.servlet.view.InternalResourceViewResolver"

id="internalResourceViewResolver">

5、修改web.xml

xmlns="http://java.sun.com/xml/ns/javaee"

xsi:schemaLocation="http://java.sun.com/xml/ns/javaee http://java.sun.com/xml/ns/javaee/web-app_3_0.xsd"

id="WebApp_ID" version="3.0">

index.jsp

org.springframework.web.context.ContextLoaderListener

contextConfigLocation

classpath*:ApplicationContext.xml

springmvc

org.springframework.web.servlet.DispatcherServlet

contextConfigLocation

classpath*:springmvc-servlet.xml

1

springmvc

/

characterEncodingFilter

org.springframework.web.filter.CharacterEncodingFilter

encoding

UTF-8

forceEncoding

true

characterEncodingFilter

/*

之前在测试过程中，不小心把/ 写错成 /*，导致springmvc把*.jsp,*.sql,*.txt都当做txt处理，访问页面时，直接在浏览器加载了jsp源码。

导致测试页面hello.jsp中的${message}一直取不到Controller传过来的值。

springmvc

/

6、测试，项目右键->Run As->Run On Server->Tomcat...

运行成功后，访问：http://localhost:8888/SSM01/Hello/SayHello

控制台输出：输出true，表示${message}赋值成功

浏览器输出：

到此，SpringMVC搭建成功 ！！！

继续整合！！！

7、在controller包下，新建一个BookController

package com.lmei.ssm.controller;

import java.util.List;

import javax.annotation.Resource;

import org.springframework.stereotype.Controller;

import org.springframework.ui.Model;

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

import com.lmei.ssm.entity.Book;

import com.lmei.ssm.service.BookService;

@Controller

@RequestMapping("/Book")

public class BookController {

@Resource

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 "Book/index";

}

}

8、在WEB-INFO/view下新建一个文件夹Book，然后在文件夹内添加index.jsp

Book/index.jsp代码：

图书管理

9、测试

运行服务器，在浏览器访问：http://localhost:8888/SSM01/Book/getAllBook

到此，完成SpringMVC+Spring+MyBatis的整合！！！
