基於Maven工具搭建Spring+SpringMVC++MyBatis(ssm)框架步驟

阿新 • • 發佈：2018-12-22

1.使用Ecplise建立Maven工程：

2.構建SSM框架

3.日誌資訊：log4j

4.應用例項：使用者登入

5 資料庫MySQL

1.使用Ecplise建立Maven工程：

1.1 File -> New -> Other，在New視窗中選擇 Maven -> Maven Project；點選next，如下圖

maven

1.2選擇路徑，點選next，如下圖

1.3選擇專案型別選擇Artifact Id為maven-archetype-webapp那一項，如下圖

1.4 輸入Group ID和 Artifact ID，以及Package，點選finish；

Group ID:專案組織唯一識別符號，實際對應Java包的結構；

Artifact ID：專案的唯一識別符號，實際對應專案的的名稱；

1.5 點選finish後，生成的工程結構，如下圖

1.6 目錄結構和標準的maven web結構不一致，少了一個資料夾src/test/resources，我們手動建立，右鍵專案根目錄點選New -> Source Folder，建出這個資料夾，如下圖：

1.7 把專案變成Dynamic Web專案右鍵專案，properties --》Project Facets，點選Convert to faceted fro，勾上Dynamic Web Module，並將Version為3.0（Java7版本），若修改報錯，也可以將工程轉成Navigator檢視，修改.setting資料夾下的檔案；

設定部署程式集(Web Deployment Assembly)
上面步驟設定完成後，點選OK，再右鍵專案，選擇properties --》Deployment Assembly，如下圖

2.構建SSM框架

2.1 pom.xml中新增所需要的jar包：注意根據專案實際情況修改groupId、artifactId、version標籤；

儲存好pom.xml檔案後，maven會幫助我們下載所需要的jar包；

2.2 配置前端控制器DispatcherServlet：Spring MVC 提供一個名為org.springframework.web.servlet.DispatchServlet的Servlet充當前端控制器，所有的請求都由這個前端控制器來分派請求；DispatcherServlet是一個Servlet，所以使用時需要配置到Web應用部署描述符web.xml檔案中：

關鍵程式碼如下：

 <servlet>
    <!-- Servlet 名稱 -->
    <servlet-name>springmvc</servlet-name>
    <!-- Servlet 對應的java類 -->
    <servlet-class>org.springframework.web.servlet.DispatcherServlet</servlet-class>
    <!-- Servlet 的引數資訊，引數值為Spring MVC配置檔案路徑，預設會找/WEB-INF/[spring-name]-servlet.xml檔案-->
    <init-param>
      <param-name>contextConfigLocation</param-name>
      <param-value>classpath:mvc/springmvc.xml</param-value>
    </init-param>
    <!-- 在Web應用啟動時立即載入Servlet -->
    <load-on-startup>1</load-on-startup>
  </servlet>
<!-- Servlet 對映宣告 -->
  <servlet-mapping>
    <servlet-name>springmvc</servlet-name>
<!-- 監聽當前域.do的所以請求 -->
    <url-pattern>*.do</url-pattern>
  </servlet-mapping>

在web.xml檔案中，除了配置前端控制器，還需要配置工程編碼等資訊，完整配置資訊如下：

<?xml version="1.0" encoding="UTF-8"?>
<web-app xmlns:xsi="http://www.w3.org/2001/XMLSchema-instance" xmlns="http://xmlns.jcp.org/xml/ns/javaee" xsi:schemaLocation="http://xmlns.jcp.org/xml/ns/javaee http://xmlns.jcp.org/xml/ns/javaee/web-app_3_1.xsd" id="WebApp_ID" version="3.1">

  </listener>
  <servlet>
    <servlet-name>springmvc</servlet-name>
    <servlet-class>org.springframework.web.servlet.DispatcherServlet</servlet-class>
    <init-param>

  </servlet>
  <servlet-mapping>
    <servlet-name>springmvc</servlet-name>
    <url-pattern>*.do</url-pattern>
  </servlet-mapping>
</web-app>

2.4 Spring MVC配置：配置Handle、處理器對映器，處理器介面卡以及檢視解析器

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

       <property name="cache" value="true" />
		<property name="prefix" value="/freemarker/" />
		<property name="suffix" value=".html" />
    </bean>
	
</beans>

2.5 spring整合MyBatis：applicationContext.xml

</beans>

jdbc.properties（MySQL）

jdbc.driver = com.mysql.jdbc.Driver
jdbc.url = jdbc:mysql://資料庫IP:埠/資料庫名?characterEncoding=utf-8
jdbc.username = 使用者名稱
jdbc.password = 密碼

2.6 MyBatis配置：mybatis-config.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>
	
	<!-- 定義別名 減少類完全限定名的冗餘-->
	<typeAliases>
	    <package name="org.ssm"/>
	</typeAliases>

</configuration>

3.日誌資訊：log4j

3.1 log4j.properties

#將Mybatis log4j執行級別調到DEBUG可以在控制檯打印出Mybatis執行的sql語句  
log4j.rootLogger=DEBUG,Console
### 把日誌資訊輸出到控制檯 ###  
log4j.appender.Console=org.apache.log4j.ConsoleAppender  
log4j.appender.Console.Target=System.out  
log4j.appender.Console.layout = org.apache.log4j.PatternLayout  
log4j.appender.Console.layout.ConversionPattern= %5p [%t] - %m%n
  
###顯示SQL語句部分  
log4j.logger.com.mybatis=DEBUG  
log4j.logger.com.mybatis.common.jdbc.SimpleDataSource=DEBUG  
log4j.logger.com.mybatis.common.jdbc.ScriptRunner=DEBUG  
log4j.logger.com.mybatis.sqlmap.engine.impl.SqlMapClientDelegate=DEBUG  
log4j.logger.java.sql.Connection=DEBUG  
log4j.logger.java.sql.Statement=DEBUG  
log4j.logger.java.sql.PreparedStatement=DEBUG

3.2 若log4j檔案不在/WEB-INF/資料夾下，需要在web.xml中進行配置：

<!-- 載入log4j配置檔案 -->
	<context-param>
		<param-name>log4jConfigLocation</param-name>
		<param-value>classpath:properties/log4j.properties</param-value>
	</context-param>
	<listener>
		<listener-class>org.springframework.web.util.Log4jConfigListener</listener-class>
	</listener>

4.應用例項：使用者登入

4.1 建立使用者類SysUser.java和SysUserMapper.java

package org.ssm.sysMgr.sysUser.entity;

import java.util.Date;
import java.util.List;

import org.ssm.sysMgr.sysRole.entity.SysRole;
import org.apache.ibatis.type.Alias;

@Alias("SysUser")
public class SysUser {
	
	/**
	 * 使用者編號
	 */
