如何快速搭建一个ssm框架

首先我们需要创建一个maven项目

1.右键 new maven project

第一个勾选然后下一步

groupid 可以写com.xxx.xxx 之类的

artifaceid 写项目名 xxx

web项目选择打war包然后下一步就ok

2.项目中少web.xml /WEB-INFO 右键项目 properties → project faces → Dynamic Web Module 勾选去掉点击apply →再勾选上然后它会提醒你配置然后第二个框目录写src/main/webapp 应用就好了 maven的setting 路径自己配置镜像位置推荐用阿里云的

3.pom文件的配置

这里jar包miss报错还有项目红色叹号怎么弄maven update project 还有build path clean都没有用，直接去网址下载jar包然后放进文件夹里

具体的pom 需要的jar包如下


<dependencies>
  		 
		  <dependency>
		    <groupId>org.springframeworkgroupId>
		    <artifactId>spring-webmvcartifactId>
		    <version>4.3.7.RELEASEversion>
		  dependency>
		  
		  <dependency>
			    <groupId>org.springframeworkgroupId>
			    <artifactId>spring-jdbcartifactId>

  dependencies>

4.我们对WEB-INF 下的web.xml 进行编写这个分开在里面补充

1）.spring 的容器 ContextLoaderListener 快捷键补全 alt+/

classpath:applicationContext.xml

只用修改这个并且在src/main/resources 右键 new spring bean configuration File 创建上面的 spring的配置文件

2).springMVC前端控制器

DispatcherServlet 快捷键提示补全

           contextConfigLocation
           location
          删掉不指定默认全部扫描

将dispatcherServlet 全改成这个名

/ 全部扫描

然后在web.xml同级目录下创建dispatcherServlet-servlet.xml 创建方式同上applicationContext.xml

在这个里面控制springMVC扫描

3).添加两个基本的过滤器


		<filter>
			<filter-name>CharacterEncodingFilterfilter-name>
			<filter-class>org.springframework.web.filter.CharacterEncodingFilterfilter-class>
			<init-param>
				<param-name>encodingparam-name>  
				<param-value>utf-8param-value>
			init-param>
			<init-param>
				<param-name>forceRequestEncodingparam-name>  
				<param-value>trueparam-value>
			init-param>
			<init-param>
				<param-name>forceResponseEncodingparam-name>  
				<param-value>trueparam-value>
			init-param>	
		filter>
		<filter-mapping>
			<filter-name>CharacterEncodingFilterfilter-name>
			<url-pattern>/*url-pattern>  
		filter-mapping>
	 
	 <filter>
			<filter-name>HiddenHttpMethodFilterfilter-name>
			<filter-class>org.springframework.web.filter.HiddenHttpMethodFilterfilter-class>
	  filter>
	  <filter-mapping>
			<filter-name>HiddenHttpMethodFilterfilter-name>
			<url-pattern>/*url-pattern>  
		filter-mapping>

5.在dispatcherServlet-servlet.xml配置文件顶部加这个

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

然后对SpringMVC 的配置文件包含网站跳转逻辑的控制，配置即注解的扫描的范围的指定

选择该xml下面的Namespaces mvc勾选上


 <context:component-scan base-package="com.ice" use-default-filters="false">
 <context:include-filter type="annotation" expression="org.springframework.stereotype.Controller"/>
 context:component-scan>
 
 <bean class="org.springframework.web.servlet.view.InternalResourceViewResolver">
     <property name="prefix" value="/WEB-INF/views/">property>   
     <property name="suffix" value=".jsp">property>    
 bean>
 
 
 <mvc:default-servlet-handler/>
 <mvc:annotation-driven>
 
 mvc:annotation-driven>

6. 配置c3p0数据库相关

在applicationContext.xml 文件打开然后选择namespace aop（√） context (√） tx(√）


 
<context:component-scan base-package="com.ice">
  <context:exclude-filter type="annotation" expression="org.springframework.stereotype.Controller"/> 
context:component-scan>
 
<context:property-placeholder location="classpath:dbconfig.properties"/>
<bean  id="pooledDataSource" class="com.mchange.v2.c3p0.ComboPooledDataSource">
 <property name="jdbcUrl" value="${jdbc.jdbcUrl}">property>
 <property name="driverClass"  value="${jdbc.driverClass}">property>
 <property name="user" value="${jdbc.user}">property>
 <property name="password" value="${jdbc.password}">property>
bean>
 
 
<bean  id="SqlSessionFactory" class="org.mybatis.spring.SqlSessionFactoryBean">
    
    <property name="configLocation" value="classpath:mybatis-config.xml">property>
    
    <property name="dataSource" ref="pooledDataSource">property>
    
    <property name="mapperLocations" value="classpath:mapper/*.xml">property>
 bean>
 
 
 
 <bean class="org.mybatis.spring.mapper.MapperScannerConfigurer">
 
   <property name="basePackage" value="com.ice.dao">property>
 
 
 
 <bean  id="transactionManager" class="org.springframework.jdbc.datasource.DataSourceTransactionManager">
    <property name="dataSource" ref="pooledDataSource">property>  
 bean>
 
 <aop:config>
 
 <aop:pointcut expression="execution(* com.ice.service..*(..))" id="txPoint"/>
 
 <aop:advisor advice-ref="txAdvice" pointcut-ref="txPoint"/>
 aop:config>
 
 <tx:advice id="txAdvice" >
   <tx:attributes>
     <tx:method name="*"/>  
     <tx:method name="get*" read-only="true"/>
   tx:attributes>
 tx:advice>

此步骤创建了 mapper包同时还有mybatis的配置文件 mybatis-config.xml 与applicationContext在同一目录下

7.mybatis的配置 mybatis-config.xml的主要配置如下


"1.0" encoding="UTF-8"?>
configuration
  PUBLIC "-//mybatis.org//DTD Config 3.0//EN"
  "http://mybatis.org/dtd/mybatis-3-config.dtd">   
  
  <configuration>
    <settings>
       <setting name="mapUnderscoreToCamelCase" value="true"/> 
    settings>
    <typeAliases >
     <package  name="com.ice.bean" />
    typeAliases>
  configuration>

然后就是 mybatis逆向工程必须的xml 和java类

这个是xxx.xml 直接放在包下面跟pom.xml同级


"1.0" encoding="UTF-8"?>
generatorConfiguration
  PUBLIC "-//mybatis.org//DTD MyBatis Generator Configuration 1.0//EN"
  "http://mybatis.org/dtd/mybatis-generator-config_1_0.dtd">
<generatorConfiguration>
    
    
    <context id="cosmetic"   targetRuntime="MyBatis3">
        <commentGenerator>
            <property name="suppressDate" value="true"/>
            
            <property name="suppressAllComments" value="true"/>
        commentGenerator>
        
        
        
        <jdbcConnection driverClass="com.mysql.jdbc.Driver" connectionURL="jdbc:mysql://192.168.204.131:3306/ssh_crud" userId="root" password="123456">
        jdbcConnection>
   
         
        <javaTypeResolver>
            <property name="forceBigDecimals" value="false"/>
        javaTypeResolver>
        
        
        <javaModelGenerator targetPackage="com.ice.bean" targetProject=".\src\main\java">
            <property name="enableSubPackages" value="true"/>
            <property name="trimStrings" value="true"/>
        javaModelGenerator>
        
        
        
        <sqlMapGenerator targetPackage="com.ice.dao" targetProject=".\src\main\java">
            <property name="enableSubPackages" value="true"/>
        sqlMapGenerator>
        
        
        
        <javaClientGenerator type="XMLMAPPER" targetPackage="com.ice.dao" targetProject=".\src\main\java">
            <property name="enableSubPackages" value="true"/>
        javaClientGenerator>
        
        
        
        <table  tableName="emp"   domainObjectName="Employee" />
        <table tableName="dept"  domainObjectName="Department" />
     
    context>
generatorConfiguration>

xxx.java


package com.ice.test;
 
import java.io.File;
import java.util.ArrayList;
import java.util.List;
 
import org.mybatis.generator.api.MyBatisGenerator;
import org.mybatis.generator.config.Configuration;
import org.mybatis.generator.config.xml.ConfigurationParser;
import org.mybatis.generator.internal.DefaultShellCallback;
 
public class MBGTest {
 
  //生成bean  mapper  的方法
	 
		public void generator() throws Exception{
	 
			List warnings = new ArrayList();
			boolean overwrite = true;
			//指定 逆向工程配置文件
			File configFile = new File("mbg.xml"); 
			ConfigurationParser cp = new ConfigurationParser(warnings);
			Configuration config = cp.parseConfiguration(configFile);
			DefaultShellCallback callback = new DefaultShellCallback(overwrite);
			MyBatisGenerator myBatisGenerator = new MyBatisGenerator(config,
					callback, warnings);
			myBatisGenerator.generate(null);
	 
		} 
		public static void main(String[] args) throws Exception {
			try {
				MBGTest generatorSqlmap = new MBGTest();
				generatorSqlmap.generator();
			} catch (Exception e) {
				e.printStackTrace();
			}
			
		}
	 
	
 
}

运行上面的java 就生成了所需的 mapper 以及实体类javabean

我们的框架三部分就完成的差不多了
