MAVEN+SSM+tomcat8.5整合

maven项目比起以前确实方便了很多，但依赖关系的维护还是比较麻烦（有条件的还是换springBoot吧），这里对maven的ssm整合做个完整案例
maven：3.6
jdk：1.8 64位
windows：win10 企业版
tomcat：8.5.35

环境准备
安装maven，配置环境变量（基本使用，可省略解压即可）
Maven编译默认是jdk1.5，就算开发环境配置了，只要从新更新，就变成1.5的编译环境，修改maven的settings.xml文件

<profile>    
    <id>jdk-1.8</id>    
    <activation>    
        <activeByDefault>true</activeByDefault>    
        <jdk>1.8</jdk>    
    </activation>    
    <properties>    
        <maven.compiler.source>1.8</maven.compiler.source>    
        <maven.compiler.target>1.8</maven.compiler.target>    
        <maven.compiler.compilerVersion>1.8</maven.compiler.compilerVersion>    
    </properties>    
</profile>

一些jar包，中央仓库没有，settings.xml中配置一些远端库

<profile>
<repositories>
	<repository>
	    <id>java.net</id>
	    <url>https://maven.java.net/content/repositories/public/</url>
	</repository> 

	 <repository>
	<id>JBoss repository</id>
	<url>http://repository.jboss.org/nexus/content/groups/public/</url>
      </repository>

	  <repository>
            <id>alimaven</id>
            <name>aliyun maven</name>
            <url>http://maven.aliyun.com/nexus/content/groups/public/</url>
            <layout>default</layout>
            <snapshots>
                <enabled>false</enabled>
            </snapshots>
        </repository>

		<repository>
            <id>spring-milestones</id>
            <name>Spring Milestones</name>
            <url>https://repo.spring.io/libs-milestone</url>
            <snapshots>
                <enabled>false</enabled>
            </snapshots>
        </repository>

</repositories>
</profile>

修改settings.xml中本地库的位置（非必须，默认在用户文档文件夹下的.m2目录）

<localRepository>D:\maven-jar\repository</localRepository>

如果要将来maven直接发布到远端tomcat热部署，还需如下配置

<server>
    <id>tomcat8</id>
    <username>tomcat</username>
    <password>123456</password>
</server>

以上信息要和tomcat的用户配置一致，tomcat的apache-tomcat-8.5.35\conf\tomcat-users.xml增加

<role rolename="manager-gui"/>
<role rolename="admin-gui"/>
<role rolename="manager-script"/>
<user password="123456" roles="admin-gui,manager-gui,manager-script" username="tomcat"/>
</tomcat-users>

配置eclipse的maven用自己安装的（eclipse—window—preferences）
配置用户配置文件为自己修改好的settings.xml（我是将maven程序里的文件复制出来修改的，自己视情况而定）
配置eclipse的java环境，换成jDK 的jre
Jre由原来的用户jre编辑修改为开发jdk里的jre
创建maven项目
1. 创建一个父项目，统一依赖，以保证版本库的一致
2. New—— other—— maven——pom（容器）——指定gav坐标
修改pom文件，添加依赖关系
a) 将多处使用的信息提取出来，例如版本号
b) 我们案例里面引用自己的jar包
将原maven工程引入，建立依赖关系
Maven——install 将jar包加入本地库
c) 只有jar包时，使用maven指令（配置好环境变量——配置文件使用的是maven安装目录下的settings.xml）

mvn install:install-file -Dfile=D:\maven-jar\teacherXue-tools-0.0.1-SNAPSHOT.jar -DgroupId=com.issCollege -DartifactId=teacherXue-tools -Dversion=1.0.0 -Dpackaging=jar

e) 后续项目都继承于父项目，父项目修改了依赖版本，则子项目同步改变，非常方便

创建本次maven演示项目
a) 新建maven项目，类型为war
b) 继承于上面创建的parent项目，这里就不需要在配置依赖

MAVEN+SSM+tomcat8.5整合
7.本War项目要如下调整，确认动态站点版本为3.1，java为1.8

8.生成web项目所需的目录结构和web.xml，项目上鼠标右键——javaEE——Generate Deploy

9. 修改当前项目的web.xml的DTD为

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

可以从tomcat的web.xml复制
10.项目上右键，run as——maven build 配置maven-tomcat运行命令clean install tomcat7:redeploy，以后右键 run as——maven build即可
MAVEN+SSM+tomcat8.5整合
11.如果热部署的tomcat不是本机（是网络中其他计算机）则需要修改apache-tomcat-8.5.35\webapps\manager\META-INF\context.xml设置允许非本机访问

<Valve className="org.apache.catalina.valves.RemoteAddrValve"
         allow="127\.\d+\.\d+\.\d+|::1|0:0:0:0:0:0:0:1" />

改为

<Valve className="org.apache.catalina.valves.RemoteAddrValve"
         allow="^.*$" />

MAVEN+SSM+tomcat8.5整合
12.SSM整合

可以先使用mybatis的****生成基本的po和mapper
创建mybatis的配置文件，里面只有日志、别名和分页插件

<configuration>
<!-- 	<settings>
		<setting name="logImpl" value="STDOUT_LOGGING" />
	</settings> -->
	<typeAliases>
		<package name="com.issCollege.stumanager.po" />
	</typeAliases>
	<plugins>
		<plugin interceptor="com.github.pagehelper.PageInterceptor">
			<!-- 4.0.0以后版本可以不设置该参数 -->
			<!-- <property name="dialect" value="mysql"/> -->
			<!-- 该参数默认为false -->
			<!-- 设置为true时，会将RowBounds第一个参数offset当成pageNum页码使用 -->
			<!-- 和startPage中的pageNum效果一样 -->
			<property name="offsetAsPageNum" value="true" />
			<!-- 该参数默认为false -->
			<!-- 设置为true时，使用RowBounds分页会进行count查询 -->
			<property name="rowBoundsWithCount" value="true" />
			<!-- 设置为true时，如果pageSize=0或者RowBounds.limit = 0就会查询出全部的结果 -->
			<!-- （相当于没有执行分页查询，但是返回结果仍然是Page类型） -->
			<property name="pageSizeZero" value="true" />
			<!-- 3.3.0版本可用 - 分页参数合理化，默认false禁用 -->
			<!-- 启用合理化时，如果pageNum<1会查询第一页，如果pageNum>pages会查询最后一页 -->
			<!-- 禁用合理化时，如果pageNum<1或pageNum>pages会返回空数据 -->
			<property name="reasonable" value="true" />
			<!-- 3.5.0版本可用 - 为了支持startPage(Object params)方法 -->
			<!-- 增加了一个`params`参数来配置参数映射，用于从Map或ServletRequest中取值 -->
			<!-- 可以配置pageNum,pageSize,count,pageSizeZero,reasonable,orderBy,不配置映射的用默认值 -->
			<!-- 不理解该含义的前提下，不要随便复制该配置 -->
			<property name="params"
				value="pageNum=start;pageSize=limit;" />
			<!-- 支持通过Mapper接口参数来传递分页参数 -->
			<property name="supportMethodsArguments" value="true" />
			<!-- always总是返回PageInfo类型,check检查返回类型是否为PageInfo,none返回Page -->
			<property name="returnPageInfo" value="check" />
		</plugin>
	</plugins>
</configuration>

13.创建spring—IOC的配置文件，完成数据源、事务管理、切面的相关的配置

<context:property-placeholder location="classpath:dbcfg.properties" />
	<bean class="com.alibaba.druid.pool.DruidDataSource"
		id="dataSource">
		<property name="driverClassName" value="${jdbc_driver}"></property>
		<property name="url" value="${jdbc_url}"></property>
		<property name="username" value="${jdbc_user}"></property>
		<property name="password" value="${jdbc_password}"></property>
		
	</bean>
	<!-- 会话工厂 -->
	<bean class="org.mybatis.spring.SqlSessionFactoryBean"
		id="sqlSessionFactoryBean">
		<property name="dataSource" ref="dataSource"></property>
		<property name="configLocation"
			value="classpath:mybatis-config.xml"></property>
		<property name="mapperLocations"
			value="classpath:com/issCollege/stumanager/mapper/*.xml"></property>
	</bean>
	<!-- 事务管理器 -->
	<bean
		class="org.springframework.jdbc.datasource.DataSourceTransactionManager"
		id="dataSourceTransactionManager">
		<property name="dataSource" ref="dataSource"></property>
	</bean>
	<!-- 事务注解驱动，注解@Transactional的类和方法将具有事务性 -->
	<tx:annotation-driven
		transaction-manager="dataSourceTransactionManager" />
	<!-- spring和mybatis的整合 -->
	<bean class="org.mybatis.spring.mapper.MapperScannerConfigurer">
		<property name="basePackage" value="com.issCollege.stumanager.mapper"></property>
	</bean>
	
	<!-- 配置事务处理 -->
	<!-- <tx:advice transaction-manager="transactionManager" id="txadvice">
		<tx:attributes>
			<tx:method name="add*" propagation="REQUIRED" />
			<tx:method name="insert*" propagation="REQUIRED" />
			<tx:method name="delete*" propagation="REQUIRED" />
			<tx:method name="update*" propagation="REQUIRED" />

			<tx:method name="find*" propagation="SUPPORTS" read-only="true" />
			<tx:method name="get*" propagation="SUPPORTS" read-only="true" />
			<tx:method name="select*" propagation="SUPPORTS" read-only="true" />
			<tx:method name="list*" propagation="SUPPORTS" read-only="true" />
		</tx:attributes>
	</tx:advice>
	
	<aop:config>
		<aop:pointcut expression="execution(* com.issCollege.banbiShop.service.*.*(..))"
			id="txpointcut" />
		<aop:advisor advice-ref="txadvice" pointcut-ref="txpointcut" />
	</aop:config>
</beans> -->
4)	创建springMVC的配置文件，完成controller和注解驱动、转换器等的配置
<!-- 扫描包实例化对象 -->
	<context:component-scan
		base-package="com.issCollege.stumanager"></context:component-scan>
	<!-- 注解驱动注册 -->
	<mvc:annotation-driven
		conversion-service="conversionServiceFactoryBean">

		<mvc:message-converters>
			<!-- 设置返回字符串编码 -->
			<bean id="stringHttpMessageConverter"
				class="org.springframework.http.converter.StringHttpMessageConverter">
				<property name="supportedMediaTypes">
					<list>
						<value>text/html;charset=UTF-8</value>
						<value>application/json;charset=UTF-8</value>
					</list>
				</property>
			</bean>
			<!-- json转换器 -->
			<bean id="mappingJackson2HttpMessageConverter"
				class="org.springframework.http.converter.json.MappingJackson2HttpMessageConverter">
				<property name="supportedMediaTypes">
					<list>
						<value>text/html;charset=UTF-8</value>
						<value>application/json;charset=UTF-8</value>
					</list>
				</property>
			</bean>
		</mvc:message-converters>

	</mvc:annotation-driven>
	<bean
		class="org.springframework.format.support.FormattingConversionServiceFactoryBean"
		id="conversionServiceFactoryBean">
		<property name="converters">
			<list>
				<bean
					class="com.issCollege.stumanager.converter.StringToDateConverter"></bean>

			</list>
		</property>
	</bean>
	<!-- 对模型视图名称的解析，即在模型视图名称添加前后缀 -->
	<bean
		class="org.springframework.web.servlet.view.InternalResourceViewResolver">
		<property name="prefix" value="/WEB-INF/jsp/"></property>
		<property name="suffix" value=".jsp"></property>
	</bean>
	<!-- 配置文件上传 -->
	<bean
		class="org.springframework.web.multipart.commons.CommonsMultipartResolver"
		id="multipartResolver">
		<property name="defaultEncoding" value="UTF-8"></property>
		<property name="maxUploadSize" value="99999999"></property>
	</bean>
	<!-- 启动切面注入代理 -->
	<aop:aspectj-autoproxy proxy-target-class="true" />

13.配置当前项目的web.xml文件
a) MVC 依靠servlet来实例化
b) IOC要靠监听器来实例化

 <!-- 加载Spring容器 -->
   <context-param>
        <param-name>contextConfigLocation</param-name>
        <param-value>
            classpath:spring-tran.xml
        </param-value>
    </context-param>
    
    <listener>
    <display-name>springIOC</display-name>
    <listener-class>org.springframework.web.context.ContextLoaderListener</listener-class>
    </listener>
    

    
    <!-- 定义前端控制器 -->
  <servlet>
    <servlet-name>spring-mvc</servlet-name>
    <servlet-class>org.springframework.web.servlet.DispatcherServlet</servlet-class>
    <!-- 指定路径 -->
    <init-param>
        <param-name>contextConfigLocation</param-name>
        <param-value>classpath:spring-mvc.xml</param-value>
    </init-param>
    <!-- 随spring启动而启动 -->
    <load-on-startup>1</load-on-startup>
  </servlet>

  <servlet-mapping>
    <servlet-name>spring-mvc</servlet-name>
    <url-pattern>*.action</url-pattern>
  </servlet-mapping>

  <!-- 工程编码过滤器 -->
    <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>
        <init-param>
            <param-name>forceEncoding</param-name>
            <param-value>true</param-value>
        </init-param>
    </filter>
    <filter-mapping>
        <filter-name>encodingFilter</filter-name>
        <url-pattern>/*</url-pattern>
    </filter-mapping>

14.如果远程打包热部署，需要配置pom文件，将项目的XML配置文件打包进去，在pom的build里增加

<resources>
			<resource>
				<directory>src/main/java</directory>
				<includes>
					<include>**/*.xml</include>
				</includes>
				<filtering>false</filtering>
			</resource>
			<resource>
				<directory>src/main/resources</directory>
				<includes>
					<include>*.xml</include>
				</includes>
				<filtering>false</filtering>
			</resource>
		</resources>

部署运行时，先确保远程tomcat启动中，项目右键maven build没错误即可访问目标服务器。
如果要本地tomcat调试，需要在eclipse里设置本地tomcat
本地eclipse关联的tomcat服务器双击（停止状态，无项目，有先移除并clean），选中server options里的publish module context to separate XML files，让服务器使用本项目的XML配置文件

同志们，可以试试了
