SSM整合的一些配置(基于Maven工程,逆向工程，Restful风格)

自己在学习SSM过程中，一直没有整理过关于如何整个整合配置的，这次基于Maven的SSM配置整理一遍。

1.首先，创建一个Maven工程。在创建Maven工程开始时，一定要把圈住的对号打上，要不可能会出现错误。

2.之后会Next，会出现如下，Group Id和Artifact Id就是Maven的pom.XML配置文件的坐标。其中Artifact Id也是工程的名字，Version选择默认的就可以。Packaging选择war形式的，因为war形式的创建出来的工程才是web工程.其他的不需要填就可以.

3. ①在创建Maven之后可能在pom.xml文件中出现小红叉，有两处要修改。第一处，右键工程--->Maven--->Update Project，之后打上对号。之后等一会就可以了。

②这是可能pom.xml文件还会有小红叉，这是需要创建web需要的一些配置。右键工程--->properties.这时Dynamic Web Module是勾选的，把勾选的勾掉，点击Apply，别点Ok，再把Dynamic Web Module勾选。这是下面会有选项，点击.

③之后就是web的一些配置要放的位置，把这些配置放到相对应的位置就可以了。

4.之后Maven工程就创建完成。来看一下工程结构。src/main/java写源代码的目录，src/main/resource放配置文件的地方，web的一些配置就放在了src/main/webapp下了

5.web.xml配置

<?xml version="1.0" encoding="UTF-8"?>
<web-app version="2.5" 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_2_5.xsd">
	
	<!-- Spring配置 -->

	</context-param>

	<!-- Bootstraps the root web application context before servlet initialization -->
	<listener>
		<listener-class>org.springframework.web.context.ContextLoaderListener</listener-class>
	</listener>
	
	<!--springMvc配置  -->
	<servlet>

		<init-param>
			<param-name>contextConfigLocation</param-name>
			<param-value>classpath:springmvc.xml</param-value>

		<load-on-startup>1</load-on-startup>
	</servlet>

	<!-- Map all requests to the DispatcherServlet for handling -->
	<servlet-mapping>
		<servlet-name>springDispatcherServlet</servlet-name>
		<url-pattern>/</url-pattern>
	</servlet-mapping>
	
	<!-- 配置字符编码过滤器,此Filter要放在第一个位置上 -->
	<filter>

		<filter-class>org.springframework.web.filter.CharacterEncodingFilter</filter-class>

	</filter>
	<filter-mapping>
		<filter-name>characterEncodingFilter</filter-name>
		<url-pattern>/*</url-pattern>
	</filter-mapping>
	
	
	<!-- 配置REST风格的URL,配置过滤器 -->
	<filter>

	</filter>
	<filter-mapping>

	</filter-mapping>
	
	<!-- 在ajax中，type类型为PUT或者DELETE时，可以直接发送 -->
	<filter>
		<filter-name>HttpPutFormContentFilter</filter-name>
		<filter-class>org.springframework.web.filter.HttpPutFormContentFilter</filter-class>
	</filter>
	<filter-mapping>
		<filter-name>HttpPutFormContentFilter</filter-name>
		<url-pattern>/*</url-pattern>
	</filter-mapping>
	
</web-app>

6.spring的applicationContext.xml的配置文件

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

			<tx:method name="*"/>
			<tx:method name="get*" read-only="true"/>
		</tx:attributes>
	</tx:advice>
</beans>

7.Springmvc的配置

<?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"

	<!-- 只扫描Controller -->
	<context:component-scan base-package="com.an.crud" use-default-filters="false">
		<context:include-filter type="annotation" expression="org.springframework.stereotype.Controller"/>
	</context:component-scan>
	
	<!-- 视图解析器 -->
	<bean class="org.springframework.web.servlet.view.InternalResourceViewResolver">
		<property name="prefix" value="/WEB-INF/pages/"></property>
		<property name="suffix" value=".jsp"></property>
	</bean>
	
	<!-- 处理静态资源 -->
	<mvc:default-servlet-handler/>
	<!-- 这个一般都要配,必配 -->
	<mvc:annotation-driven />
</beans>

8.mybatis-config配置

<?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>
	<settings>

	<!-- 分页插件 -->
	<plugins>
		<plugin interceptor="com.github.pagehelper.PageInterceptor">
			<!-- 分页参数合理化 -->
			<property name="reasonable" value="true"/>
		</plugin>
	</plugins>
</configuration>

9.Maven中pom.xml中的依赖

<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/xsd/maven-4.0.0.xsd">

10.逆向工程的mbg.xml配置

<?xml version="1.0" encoding="UTF-8"?>
<!DOCTYPE generatorConfiguration
  PUBLIC "-//mybatis.org//DTD MyBatis Generator Configuration 1.0//EN"
  "http://mybatis.org/dtd/mybatis-generator-config_1_0.dtd">

<generatorConfiguration>

  <context id="DB2Tables" targetRuntime="MyBatis3">
  	
  	<!-- 配置生成的文件都没有注释 -->
  	<commentGenerator>
  		<property name="suppressAllComments" value="true" />
  	</commentGenerator>
  	<!-- 配置数据源 -->
    <jdbcConnection driverClass="com.mysql.jdbc.Driver"
        connectionURL="jdbc:mysql:///ssm_crud"
        userId="root"
        password="1234">
    </jdbcConnection>
	
    <javaTypeResolver>
      <property name="forceBigDecimals" value="false" />
    </javaTypeResolver>
	
	<!-- 配置javaBean生成的位置-->
    <javaModelGenerator targetPackage="com.an.crud.bean" targetProject=".\src\main\java">
      <property name="enableSubPackages" value="true" />
      <property name="trimStrings" value="true" />
    </javaModelGenerator>

	<!-- 配置sql映射文件生成的位置mapper -->
    <sqlMapGenerator targetPackage="mapper"  targetProject=".\src\main\resources">
      <property name="enableSubPackages" value="true" />
    </sqlMapGenerator>
	
	<!-- 配置指定mapper接口生成的位置 -->
    <javaClientGenerator type="XMLMAPPER" targetPackage="com.an.crud.mapper"  targetProject=".\src\main\java">
      <property name="enableSubPackages" value="true" />
    </javaClientGenerator>

	<!-- table指定每个表的生成策略 -->
	<!-- tableName:对应的表      domainObjectName:生成的bean实例对象 -->
    <table tableName="tb_emp" domainObjectName="Employee"></table>
	<table tableName="tb_dept" domainObjectName="Department"></table>
  </context>
</generatorConfiguration>

11.生成逆向工程的测试：

package com.an.crud.test;

import java.io.File;
import java.util.ArrayList;
import java.util.List;

import org.junit.Test;
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 TestMBG {
	@Test
	public void test1() throws Exception{
	   List<String> warnings = new ArrayList<String>();
	   boolean overwrite = true;
	   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);
	}
}

运行逆向工程的测试，就会生成相对应的bean、mapper等等...，目录结构如下

至此，配置基本完成了，这个简单的CRUD应用用到了BootStrap，大体是这样的，只能实现简单的增删该查，首页使用ajax实现数据交互的.

大体就这样....
