[【SSM】Eclipse使用Maven建立Web項目+整合SSM框架]css

本身接觸ssm框架有一段時間了，從最先的接觸新版ITOO項目的（SSM/H+Dobbu zk），再到本身近期來學習到的《淘淘商城》一個ssm框架的電商項目。用過，可是還真的沒有本身搭建過，一直都是用別人搭建好的。因此，從網上找了一些材料，結合本身來解決過程當中的一些問題，使本身對ssm框架理解更加深了，不爲分享，只是總結一下，下次有機會再搭建的時候，直接看本身的博客，免得找了！html

1、準備環境：
maven：apache-maven-3.2.3
jdk：jdk1.8.0_25
tomcat：tomcat-6.0.37
2、配置Maven、jdk
一、Window——>Preferences——>Maven——>設置本身的Settings
二、Window——>Preferences——>Java——>Installed JREs——>Add
java

配置好maven以後，就能夠在本地設置好的地方看到對應的Maven文件了，還有包含resp文件夾

3、新建Maven項目：
一、右擊——>New（或者是File——>New）——>other——>Maven——>Maven Project——>Nextmysql

二、這時候，咱們就成功建立出一個Maven項目了，項目結構以下圖：web

三、右擊項目，選擇Properties進行一些配置：spring

到這裏，咱們的Maven項目就建好了，接下來，咱們來整合搭建SSM（[spring](http://lib.csdn.net/base/javaee) MVC + Spring + Mybatis）

首先咱們來配置一些整合框架所必需要的jar包，也就是來配置咱們的pom文件，而後直接alt+f5，保存後，就會自動下載，存放在以前配置好的本地maven倉庫中。
pox.xml配置依賴的內容：sql

    <build>    
      <finalName>Maven_Project</finalName>    
    </build>    
</project>

二、在src/main/resources下添加配置文件：applicationContext.xml:數據庫

<?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:p="http://www.springframework.org/schema/p"    
    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-3.1.xsd      
                        http://www.springframework.org/schema/context      
                        http://www.springframework.org/schema/context/spring-context-3.1.xsd      
                        http://www.springframework.org/schema/mvc      
                        http://www.springframework.org/schema/mvc/spring-mvc-4.0.xsd">    
                            
    <!-- 使用註解式注入 -->    
    <context:annotation-config />    
        
    <!-- 自動掃描 -->    
    <context:component-scan base-package="com.ssm" />    
        
    <!-- 導入DAO配置 -->    
    <import resource="spring-dao.xml"/>    
        
    <!-- 導入數據庫配置 -->    
    <import resource="spring-db.xml"/>    
        
    <!-- 導入數據庫配置 -->    
    <import resource="spring-tx.xml"/>    
        
</beans>

配置數據庫鏈接池：jdbc.propertiesexpress

driver=com.mysql.jdbc.Driver    
url=jdbc:mysql://localhost:3306/maven_ssm    
username=root    
password=root    
#定義初始鏈接數    
initialSize=0    
#定義最大鏈接數    
maxActive=20    
#定義最大空閒    
maxIdle=20    
#定義最小空閒    
minIdle=1    
#定義最長等待時間    
maxWait=60000

配置日誌：log4j.propertiesapache

#定義LOG輸出級別    
log4j.rootLogger=INFO,Console,File    
#定義日誌輸出目的地爲控制檯    
log4j.appender.Console=org.apache.log4j.ConsoleAppender    
log4j.appender.Console.Target=System.out    
#能夠靈活地指定日誌輸出格式，下面一行是指定具體的格式    
log4j.appender.Console.layout = org.apache.log4j.PatternLayout    
log4j.appender.Console.layout.ConversionPattern=[%c] - %m%n    
    
#文件大小到達指定尺寸的時候產生一個新的文件    
log4j.appender.File = org.apache.log4j.RollingFileAppender    
#指定輸出目錄    
log4j.appender.File.File = logs/ssm.log    
#定義文件最大大小    
log4j.appender.File.MaxFileSize = 10MB    
# 輸出因此日誌，若是換成DEBUG表示輸出DEBUG以上級別日誌    
log4j.appender.File.Threshold = ALL    
log4j.appender.File.layout = org.apache.log4j.PatternLayout    
log4j.appender.File.layout.ConversionPattern =[%p] [%d{yyyy-MM-dd HH\:mm\:ss}][%c]%m%n

配置咱們的ioc注入：spring-dao.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:p="http://www.springframework.org/schema/p"    
    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-3.1.xsd      
                        http://www.springframework.org/schema/context      
                        http://www.springframework.org/schema/context/spring-context-3.1.xsd      
                        http://www.springframework.org/schema/mvc      
                        http://www.springframework.org/schema/mvc/spring-mvc-4.0.xsd">    
                            
                            
    <!-- DAO接口所在包名，Spring會自動查找其下的類 -->    
    <bean class="org.mybatis.spring.mapper.MapperScannerConfigurer">    
        <!--basePackage指定要掃描的包，在此包之下的映射器都會被搜索到。    
         可指定多個包，包與包之間用逗號或分號分隔-->    
        <property name="basePackage" value="com.ssm.dao" />    
        <property name="sqlSessionFactoryBeanName" value="sqlSessionFactory"></property>    
    </bean>                           
                            
</beans>

spring-db.xml

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

    </bean>    
        
    <bean id="dataSource" class="org.apache.commons.dbcp.BasicDataSource" destroy-method="close">    
        <property name="driverClassName" value="${driver}" />    
        <property name="url" value="${url}" />    
        <property name="username" value="${username}" />    
        <property name="password" value="${password}" />    
        <!-- 初始化鏈接大小 -->    
        <property name="initialSize" value="${initialSize}"></property>    
        <!-- 鏈接池最大數量 -->

        <property name="dataSource" ref="dataSource" />    
        <!-- 自動掃描mapping.xml文件 -->    
        <property name="mapperLocations" value="classpath:com/ssm/mapper/*.xml"></property>    
    </bean>    
        
</beans>

配置spring的事務管理器：spring-tx.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:p="http://www.springframework.org/schema/p"    
    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-3.1.xsd      
                        http://www.springframework.org/schema/context      
                        http://www.springframework.org/schema/context/spring-context-3.1.xsd      
                        http://www.springframework.org/schema/mvc      
                        http://www.springframework.org/schema/mvc/spring-mvc-4.0.xsd">    
    
    <!-- (事務管理)transaction manager, use JtaTransactionManager for global tx -->    
    <bean id="transactionManager"    
        class="org.springframework.jdbc.datasource.DataSourceTransactionManager">    
        <property name="dataSource" ref="dataSource" />    
    </bean>    
        
</beans>

接下來，咱們來整合spring mvc：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:p="http://www.springframework.org/schema/p"    
    xmlns:context="http://www.springframework.org/schema/context"

到這裏，咱們的ssm框架就完成了，下面，咱們來個實現：
在src/main/java下分別添加咱們的dao包，service包，還有controller包.包裏面添加相應的類，效果圖以下：

UserController.java:

package com.ssm.controller;    
    
import java.util.List;    
    
import javax.annotation.Resource;    
import javax.servlet.http.HttpServletRequest;    
    
import org.springframework.stereotype.Controller;    
import org.springframework.ui.Model;    
import org.springframework.web.bind.annotation.RequestMapping;    
    
import com.ssm.dto.User;    
import com.ssm.service.IUserService;    
    
@Controller    
@RequestMapping("/user")    
public class UserController {    
    @Resource    
    private IUserService userService;    
        
    @RequestMapping("/userList")    
    public String userList(HttpServletRequest request,Model model){    
        List<User> uList = userService.getAllUser();    
        model.addAttribute("uList", uList);    
        return "userList";    
    }    
        
    @RequestMapping("/showUser")    
    public String showUser(HttpServletRequest request,Model model){    
        int userId = Integer.parseInt(request.getParameter("id"));    
        User user = userService.getUserById(userId);    
        model.addAttribute("user", user);    
        return "showUser";    
    }    
        
    @RequestMapping("/addUserUI")    
    public String addUserUI(){    
        return "addUser";    
    }    
        
    @RequestMapping("/addUser")    
    public String addUser(HttpServletRequest request,Model model){    
        User user = new User();    
        user.setName(String.valueOf(request.getParameter("name")));    
        user.setPassword(String.valueOf(request.getParameter("password")));    
        user.setAge(Integer.parseInt(String.valueOf(request.getParameter("age"))));    
        userService.addUser(user);    
        return "redirect:/user/userList";    
    }    
}

IUserDao.java:

package com.ssm.dao;    
    
import java.util.List;    
import java.util.Map;    
    
import com.ssm.dto.User;    
    
public interface IUserDao {    
        
    public User queryByPrimaryKey(Integer id);    
        
    public List<User> queryUserByBatch(Map<String,Object> params);    
        
    public void insertUser(User user);    
        
    public void insertUserByBatch(List<User> list);    
        
    public void deleteByPrimaryKey(Integer id);    
        
    public void delteUserByBatch(Map<String,Object> params);    
        
    public void updateByPrimaryKey(Integer id);    
    
    public List<User> getAllUser();    
        
}

User.java:

package com.ssm.dto;    
    
public class User {    
    private Integer id;    
    
    private String name;    
    
    private String password;    
    
    public Integer getId() {    
        return id;    
    }    
    
    public void setId(Integer 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 == null ? null : password.trim();    
    }    
}

IUserService.java:

package com.ssm.service;    
    
import java.util.List;    
    
import com.ssm.dto.User;    
    
public interface IUserService {

    public void insertUser(User user);    
    
    public void addUser(User user);    
    
    public List<User> getAllUser();    
}

UserServiceImpl.java:

package com.ssm.service.Impl;    
    
import java.util.List;    
    
import javax.annotation.Resource;    
    
import org.springframework.stereotype.Service;

接下來就是咱們的靜態頁面了jsp文件了，在WEB-INF文件夾下新建jsp文件夾，添加userinfo.jsp

userinfo.jsp:

<%@ page language="java" import="java.util.*" pageEncoding="UTF-8"%>    
<%    
String path = request.getContextPath();   
String basePath=request.getSSScheme()+"://request.getServerName()"+":"+request.getServerPort+Path+  
  "/"%>  
<!DOCTYPE HTML PUBLIC "-//W3C//DTD HTML 4.01 Transitional//EN">    
<html>    
  <head>    
    <base href="<%=basePath%>">

  <body>    
    <form id="addUser" action="user/addUser" method="post">     
        userName: <input id="name" name="name" /><br/>     
        password: <input id="password" name="password" /><br/>    
        <input type="submit" value="添加新用戶"/>     
    </form>    
  </body>    
</html>

哦,忘記配置tomcat，配置一下tomcat，而後部署發佈項目，進行測試

到此，框架成

總結：真心知道用maven以後，咱們搭框架真的方便多了，最起碼不用個頂個的去找jar包，而後逐一的導入，只須要在pom文件裏面配置一下依賴，就行了。
