71 阅读 0 评论
我是靠谱客的博主 害怕板栗，最近开发中收集的这篇文章主要介绍使用eclipse+maven搭建ssm开发环境-02，觉得挺不错的，现在分享给大家，希望可以做个参考。

概述

1.修改Pom.xml文件，下载需要的jar包

<project xmlns="http://maven.apache.org/POM/4.0.0" xmlns:xsi="http://www.w3.org/2001/XMLSchema-instance"
	xsi:schemaLocation="http://maven.apache.org/POM/4.0.0 http://maven.apache.org/maven-v4_0_0.xsd">

			</plugin>
		</plugins>
	</build>
</project>

2.创建配置文件

1).log4j.properties的内容

log4j.rootLogger=DEBUG, Console

#Console
log4j.appender.Console=org.apache.log4j.ConsoleAppender
log4j.appender.Console.layout=org.apache.log4j.PatternLayout
log4j.appender.Console.layout.ConversionPattern=%d [%t] %-5p [%c] - %m%n

2).spring-mvc.xml

<?xml version="1.0" encoding="UTF-8"?>
<beans xmlns="http://www.springframework.org/schema/beans"
    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.xsd
        http://www.springframework.org/schema/mvc http://www.springframework.org/schema/mvc/spring-mvc.xsd">

    <!-- 启动自动扫描 -->
    <context:component-scan base-package="com.peng.ssm.controller" />

    <!-- 注册MVC注解驱动 -->
    <mvc:annotation-driven />

    <!-- 静态资源可访问的设置方式 -->
    <mvc:default-servlet-handler />

    <!-- 配置视图解析器，可以显式设置，也可以不设置，不设置会依据SpringMVC的默认设置 -->
    <bean id="viewResolver"
        class="org.springframework.web.servlet.view.InternalResourceViewResolver">
        <property name="prefix" value="/" />
        <property name="suffix" value=".jsp" />
    </bean>
</beans>

3).spring-mybatis.xml

<?xml version="1.0" encoding="UTF-8"?>
<beans xmlns="http://www.springframework.org/schema/beans"
	xmlns:xsi="http://www.w3.org/2001/XMLSchema-instance" xmlns:tx="http://www.springframework.org/schema/tx"
	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/tx    
        http://www.springframework.org/schema/tx/spring-tx.xsd
        http://www.springframework.org/schema/context 
        http://www.springframework.org/schema/context/spring-context-3.1.xsd  ">

	<!-- 自动扫描 -->
	<context:component-scan base-package="com.peng.ssm" />

	<!-- 引入配置文件 -->
	<bean id="propertyConfigurer"
		class="org.springframework.beans.factory.config.PropertyPlaceholderConfigurer">
		<property name="location" value="classpath:jdbc.properties" />
	</bean>

	<!-- 定义数据源Bean -->
	<!-- Druid -->
	<bean id="dataSource" class="com.alibaba.druid.pool.DruidDataSource">
		<property name="driverClassName" value="${driver}" />
		<property name="url" value="${url}" />
		<property name="username" value="${username}" />
		<property name="password" value="${password}" />
		<!-- 初始化连接大小 --> 
        <property name="initialSize" value="${initialSize}"></property> 
        <!-- 连接池最大数量 -->

        <!-- 获取连接最大等待时间 --> 
        <property name="maxWait" value="${maxWait}"></property> 
	</bean>

	<!-- 注册SqlSessionFactoryBean -->
	<bean id="sqlSessionFactory" class="org.mybatis.spring.SqlSessionFactoryBean">
		<property name="dataSource" ref="dataSource" />
		<!-- 自动扫描mappers.xml文件 -->
		<property name="mapperLocations" value="classpath:mappers/*Mapper.xml" />
	</bean>

	<!-- DAO接口所在包名，Spring会自动查找其下的类 -->
	<bean class="org.mybatis.spring.mapper.MapperScannerConfigurer">
		<property name="basePackage" value="com.peng.ssm.dao" />
		<property name="sqlSessionFactoryBeanName" value="sqlSessionFactory" />
	</bean>

	<!-- (事务管理)transaction manager, use JtaTransactionManager for global tx -->
	<bean id="transactionManager"
		class="org.springframework.jdbc.datasource.DataSourceTransactionManager">
		<property name="dataSource" ref="dataSource" />
	</bean>


</beans>

4).修改web.xml

<?xml version="1.0" encoding="UTF-8"?>  
<web-app  
        version="3.0"  
        xmlns="http://java.sun.com/xml/ns/javaee"  
        xmlns:xsi="http://www.w3.org/2001/XMLSchema-instance"  
        xsi:schemaLocation="http://java.sun.com/xml/ns/javaee http://java.sun.com/xml/ns/javaee/web-app_3_0.xsd">  
   
	<context-param>
		<param-name>contextConfigLocation</param-name>
		<param-value>classpath:spring-mybatis.xml</param-value>
	</context-param>

	<context-param>
		<param-name>log4jConfigLocation</param-name>
		<param-value>classpath:log4j.properties</param-value>
	</context-param>

	<!-- 编码过滤器 -->
	<filter>
		<filter-name>encodingFilter</filter-name>
		<filter-class>org.springframework.web.filter.CharacterEncodingFilter</filter-class>
		<init-param>
			<param-name>encoding</param-name>
			<param-value>UTF-8</param-value>
		</init-param>
	</filter>
	<filter-mapping>
		<filter-name>encodingFilter</filter-name>
		<url-pattern>/*</url-pattern>
	</filter-mapping>

	<!-- spring监听器 -->
	<listener>
		<listener-class>org.springframework.web.context.ContextLoaderListener</listener-class>
	</listener>

	<!-- spring mvc servlet -->
	<servlet>
		<servlet-name>SpringMVC</servlet-name>
		<servlet-class>org.springframework.web.servlet.DispatcherServlet</servlet-class>
		<init-param>
			<param-name>contextConfigLocation</param-name>
			<param-value>classpath:spring-mvc.xml</param-value>
		</init-param>
		<load-on-startup>1</load-on-startup>
	</servlet>
	<servlet-mapping>
		<servlet-name>SpringMVC</servlet-name>
		<!-- 此处也可以配置成 *.do 形式 -->
		<url-pattern>/</url-pattern>
	</servlet-mapping>

	<welcome-file-list>
		<welcome-file>/index.jsp</welcome-file>
	</welcome-file-list>

</web-app>

5).jdbc.properties

driver=com.mysql.jdbc.Driver 
url=jdbc:mysql://localhost:3306/test 
username=root
password=123456
initialSize=0  
maxActive=20   
maxIdle=20 
minIdle=1   
maxWait=60000

 

3.编写服务器端代码

1).创建student表

2).创建目录结构

   

1).实体类

package com.peng.ssm.entity;

public class Student {

	private int id;
	
	private String sname;
	
	private int sage;

	public int getId() {
		return id;
	}

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

	public String getSname() {
		return sname;
	}

	public void setSname(String sname) {
		this.sname = sname;
	}

	public int getSage() {
		return sage;
	}

	public void setSage(int sage) {
		this.sage = sage;
	}

	@Override
	public String toString() {
		return "Student [id=" + id + ", sname=" + sname + ", sage=" + sage + "]";
	}
	
	
}

2).DAO接口

package com.peng.ssm.dao;

import java.util.List;

import com.peng.ssm.entity.Student;

public interface StudentDao {

	public List<Student> selectAll();
	
}

3).Mapper文件

StudentMapper.XML用来编写SQL语句

<?xml version="1.0" encoding="UTF-8"?>
<!DOCTYPE mapper PUBLIC "-//mybatis.org//DTD Mapper 3.0//EN"
        "http://mybatis.org/dtd/mybatis-3-mapper.dtd">
<mapper namespace="com.peng.ssm.dao.StudentDao">

    <select id="selectAll" resultType="com.peng.ssm.entity.Student">
        select * from student 
    </select>
    
</mapper>

3).Service接口和实现类

package com.peng.ssm.service.impl;

import java.util.List;

import org.springframework.beans.factory.annotation.Autowired;
import org.springframework.stereotype.Service;

import com.peng.ssm.dao.StudentDao;
import com.peng.ssm.entity.Student;
import com.peng.ssm.service.StudentService;

@Service
public class StudentServiceImpl implements StudentService{

	@Autowired
	private StudentDao dao;
	
	@Override
	public List<Student> selectAll() {
		return dao.selectAll();
	}

}

4).Controller

package com.peng.ssm.controller;

import java.util.List;

import org.springframework.beans.factory.annotation.Autowired;
import org.springframework.stereotype.Controller;
import org.springframework.web.bind.annotation.RequestMapping;
import org.springframework.web.servlet.ModelAndView;

import com.peng.ssm.entity.Student;
import com.peng.ssm.service.StudentService;

@Controller
@RequestMapping("/student")
public class StudentController {

	  @Autowired
	  private StudentService service;
	  
	  @RequestMapping("/select")
	  public ModelAndView select(){
		  List<Student> list = service.selectAll();
		  ModelAndView mv = new ModelAndView();
		  mv.setViewName("show");
		  mv.addObject("list", list);
		  return mv;
	  }
}

5).在webapp下新建一个show.jsp

<%@ page language="java" contentType="text/html; charset=UTF-8"
    pageEncoding="UTF-8"%>
<%@ taglib prefix="c" uri="http://java.sun.com/jsp/jstl/core"%>    
<!DOCTYPE html PUBLIC "-//W3C//DTD HTML 4.01 Transitional//EN" "http://www.w3.org/TR/html4/loose.dtd">
<html>
<head>
<meta http-equiv="Content-Type" content="text/html; charset=UTF-8">
<title>学生展示</title>
</head>
<body>

	<c:forEach var="s" items="${requestScope.list }">
		${s.id } - ${s.sname } - ${s.sage } <br/>
	</c:forEach>

</body>
</html>

4.部署项目进行测试
