SSM项目搭建

SSM是最简单的项目架构，但时间久了便忘了，今天在此记录下.

创建 Maven 父工程

通过：Create New Project -> Maven，创建父工程,不需要勾选骨架，可以删除src。

然后再创建子项目同样可删除src,然后在子项目中创建模块，我这里创建了三个子模块 ，如下图：

再来一个web模块，并且在pom.xml中添加如下代码，告诉这是个war包：

 <packaging>war</packaging>

然后web模块F4进行如下配置添加WEB.xml：

配置完成后，如下：

然后在父项目中的pom.xml里添加依赖版本：

代码如下：

                </plugin>
            </plugins>
        </pluginManagement>
    </build>
</project>

 这样就可以在子模块中添加相关依赖了，与spring相关的依赖放在service模块中，与springMVC相关的依赖放在web模块中，与数据库相关的依赖放在mapper模块中。

在mapper模块添加对pojo的依赖，代码如下：

 <dependencies>
        <dependency>
            <groupId>sn.sxt</groupId>
            <artifactId>ego-manager-pojo</artifactId>
            <version>1.0-SNAPSHOT</version>
        </dependency>
    </dependencies>

在service添加对mapper的依赖以及spring的依赖，代码如下：

 <dependency>
            <groupId>sn.sxt</groupId>
            <artifactId>ego-manager-mapper</artifactId>
            <version>1.0-SNAPSHOT</version>
        </dependency>
        <dependency>
            <groupId>org.springframework</groupId>
            <artifactId>spring-context</artifactId>
        </dependency>
        <dependency>
            <groupId>org.springframework</groupId>
            <artifactId>spring-jdbc</artifactId>
        </dependency>
        <dependency>
            <groupId>org.aspectj</groupId>
            <artifactId>aspectjrt</artifactId>
            <version>1.8.12</version>
        </dependency>
        <dependency>
            <groupId>org.aspectj</groupId>
            <artifactId>aspectjweaver</artifactId>
            <version>1.8.12</version>
        </dependency>

再在web中添加对service的依赖以及springMVC依赖，代码如下：

    <dependencies>
        <dependency>
            <groupId>org.springframework</groupId>
            <artifactId>spring-webmvc</artifactId>
        </dependency>
        <dependency>
            <groupId>sn.sxt</groupId>
            <artifactId>ego-manager-service</artifactId>
            <version>1.0-SNAPSHOT</version>
        </dependency>
    </dependencies>

上面我们已经在service里添加了spring的依赖，还需要在resources添加applicationContext.xml,在此之前我们需要创建

sn.sxt.ego.manager.service包

代码如下

    <!--扫描sn.sxt.ego.manager-->
    <context:component-scan use-default-filters="true" base-package="sn.sxt.ego.manager">
<!--除开controller-->
<context:exclude-filter expression="org.springframework.stereotype.Controller" type="annotation"/>
</context:component-scan>

再在web里创建spring-servlet.xml文件并添加视图解析器，代码如下

<!--扫描sn.sxt.ego.manager-->
    <context:component-scan use-default-filters="false" base-package="sn.sxt.ego.manager">
        <!--只扫描Controller-->
        <context:include-filter expression="org.springframework.stereotype.Controller" type="annotation"/>
    </context:component-scan>
    <!--映射器和适配器的简写配置--> 
<mvc:annotation-driven/> 
<!--配置视图解析器--> 
<bean class="org.springframework.web.servlet.view.InternalResourceViewResolver"> 
<property value="/WEB-INF/jsp/" name="prefix"/> 
<property value=".jsp" name="suffix"/> 
</bean> 
<mvc:resources location="/" mapping="/**"/>

再在web.xm配置如下代码：

<?xml version="1.0" encoding="UTF-8"?>
<web-app 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_4_0.xsd"
         version="4.0">
    <context-param>
        <param-name>contextConfigLocation</param-name>
        <param-value>classpath:applicationContext.xml</param-value>
    </context-param>
    <listener>
        <listener-class>org.springframework.web.context.ContextLoaderListener</listener-class>
    </listener>
    <servlet>
        <servlet-name>springmvc</servlet-name>
        <servlet-class>org.springframework.web.servlet.DispatcherServlet</servlet-class>
        <init-param>
            <param-name>contextConfigLocation</param-name>
            <param-value>classpath:spring-servlet.xml</param-value>
        </init-param>
    </servlet>
    <servlet-mapping>
        <servlet-name>springmvc</servlet-name>
        <url-pattern>/</url-pattern>
    </servlet-mapping>

    <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>forceRequestEncoding</param-name>
            <param-value>true</param-value>
        </init-param>
        <init-param>
            <param-name>forceResponseEncoding</param-name>
            <param-value>true</param-value>
        </init-param>
    </filter>

    <filter-mapping>
        <filter-name>encodingFilter</filter-name>
        <url-pattern>/*</url-pattern>
    </filter-mapping>
</web-app>

还需要在web的pom.xml里配置tomcat插件，代码：

<build>
        <plugins>
            <plugin>
                <groupId>org.apache.tomcat.maven</groupId>
                <artifactId>tomcat7-maven-plugin</artifactId>
                <configuration>
                    <port>8080</port>           
                     <path>/</path>
               </configuration> 
           </plugin> 
        </plugins> 
</build>

现在配置完成，现在进行测试，在web里创建sn.sxt.ego.manager.web包，并在里面创建一个controller类，代码如下：

@RestController
public class HelloController {
    @GetMapping("/hello")
    public String hello(){
        return "hello";
    }
}

运行manager项目，运行结果如下：

hello

后续的jsp文件放在WEB-INF下面，css和js文件放在webapp下面，如下图：

我们再创建一个indexController，代码如下

@Controller
public class indexController {
    @GetMapping("/index")
    public String index(){
        return "index";
    }

访问http://localhost:8080/index，我们就可以访问jsp里的index.jsp页面了。

 现在把mybatis添加进项目中：在mapper的pom.xml里添加相关依赖：

        <!--spring和mybatis整合依赖-->
        <dependency>
            <groupId>org.mybatis</groupId>
            <artifactId>mybatis-spring</artifactId>
        </dependency>
        <!--mybatis依赖-->
        <dependency>
            <groupId>org.mybatis</groupId>
            <artifactId>mybatis</artifactId>
        </dependency>
        <!--阿里巴巴数据库连接池依赖-->
        <dependency>
            <groupId>com.alibaba</groupId>
            <artifactId>druid</artifactId>
        </dependency>
        <!--mysql依赖-->
        <dependency>
            <groupId>mysql</groupId>
            <artifactId>mysql-connector-java</artifactId>
        </dependency>
    </dependencies>
    <build>
        <resources>
            <resource>
                <directory>src/main/java</directory>
                <includes>
                    <include>**/*.xml</include>
                </includes>
            </resource>
            <resource>
                <directory>src/main/resources</directory>
            </resource>
        </resources>
    </build>

再在mapper的resource里配置三个文件，如图：

在db.properties里配置数据库连接如下

db.username=root
db.password=123456
db.url=jdbc:mysql:///ego?useUnicode=true&characterEncoding=UTF-8

dataSourceConfig.xml配置如下：

    <context:property-placeholder location="classpath:db.properties"/>
    <bean id="dataSource" class="com.alibaba.druid.pool.DruidDataSource">
        <property value="${db.url}" name="url"/>
        <property value="${db.username}" name="username"/>
        <property value="${db.password}" name="password"/>
    </bean>

mybatis-config.xml配置：

    <import resource="classpath:dataSourceConfig.xml"/> 
    <bean id="sqlSessionFactoryBean" class="org.mybatis.spring.SqlSessionFactoryBean"> 
        <property ref="dataSource" name="dataSource"/> 
        <property name="typeAliasesPackage" value="org.javaboy.ego.manager.bean"/> 
        <property name="mapperLocations">

    </bean>

更新service的applicationContext.xml文件：

    <import resource="classpath:mybatis-config.xml"/>
    <context:component-scan use-default-filters="true" base-package="sn.sxt.ego.manager">
        <context:exclude-filter expression="org.springframework.stereotype.Controller" type="annotation"/>
    </context:component-scan>
    <bean id="transactionManager" class="org.springframework.jdbc.datasource.DataSourceTransactionManager">
        <property ref="dataSource" name="dataSource"/>
    </bean>
    <tx:advice id="txAdvice" transaction-manager="transactionManager">
        <tx:attributes>
            <tx:method name="add*"/>
            <tx:method name="insert*"/>
            <tx:method name="delete*"/>
            <tx:method name="update*"/>
        </tx:attributes>
    </tx:advice>
    <aop:config>
        <aop:pointcut expression="execution(* sn.sxt.ego.manager.service.*.*(..))" id="pc1"/>
        <aop:advisor pointcut-ref="pc1" advice-ref="txAdvice"/>
    </aop:config>

 这样就是SSM框架就搭建好了！！
