ssm整合
一、导包(pom.xml文件)
1 <?xml version="1.0" encoding="UTF-8"?> 2 <project xmlns="http://maven.apache.org/POM/4.0.0" 3 xmlns:xsi="http://www.w3.org/2001/XMLSchema-instance" 4 xsi:schemaLocation="http://maven.apache.org/POM/4.0.0 http://maven.apache.org/xsd/maven-4.0.0.xsd"> 5 <modelVersion>4.0.0</modelVersion> 6 7 <groupId>aaa</groupId> 8 <artifactId>test_maven_qy97_03</artifactId> 9 <version>1.0-SNAPSHOT</version> 10 <properties> 11 <spring.version>4.3.18.RELEASE</spring.version> 12 </properties> 13 14 <dependencies> 15 <!--spring的核心的jar包--> 16 <dependency> 17 <groupId>org.springframework</groupId> 18 <artifactId>spring-core</artifactId> 19 <version>${spring.version}</version> 20 </dependency> 21 22 <dependency> 23 <groupId>org.springframework</groupId> 24 <artifactId>spring-beans</artifactId> 25 <version>${spring.version}</version> 26 </dependency> 27 28 <dependency> 29 <groupId>org.springframework</groupId> 30 <artifactId>spring-context</artifactId> 31 <version>${spring.version}</version> 32 </dependency> 33 34 <dependency> 35 <groupId>org.springframework</groupId> 36 <artifactId>spring-tx</artifactId> 37 <version>${spring.version}</version> 38 </dependency> 39 <!--spring mvc的jar包--> 40 <dependency> 41 <groupId>org.springframework</groupId> 42 <artifactId>spring-web</artifactId> 43 <version>${spring.version}</version> 44 </dependency> 45 46 <dependency> 47 <groupId>org.springframework</groupId> 48 <artifactId>spring-webmvc</artifactId> 49 <version>${spring.version}</version> 50 </dependency> 51 <!--spring jdbc的jar包--> 52 <dependency> 53 <groupId>org.springframework</groupId> 54 <artifactId>spring-jdbc</artifactId> 55 <version>${spring.version}</version> 56 </dependency> 57 58 <!--mybatis的jar包--> 59 <dependency> 60 <groupId>org.mybatis</groupId> 61 <artifactId>mybatis</artifactId> 62 <version>3.4.6</version> 63 </dependency> 64 <!--spring 和mybatis整合的中间件jar包--> 65 <dependency> 66 <groupId>org.mybatis</groupId> 67 <artifactId>mybatis-spring</artifactId> 68 <version>1.3.2</version> 69 </dependency> 70 71 <!--orace的驱动包--> 72 <dependency> 73 <groupId>com.oracle</groupId> 74 <artifactId>ojdbc6</artifactId> 75 <version>6</version> 76 </dependency> 77 <!--spring 实现文件上传的jar包--> 78 <dependency> 79 <groupId>commons-io</groupId> 80 <artifactId>commons-io</artifactId> 81 <version>1.3.2</version> 82 </dependency> 83 84 <dependency> 85 <groupId>commons-fileupload</groupId> 86 <artifactId>commons-fileupload</artifactId> 87 <version>1.2.1</version> 88 </dependency> 89 90 <!--解析json数据的jar包--> 91 <dependency> 92 <groupId>com.fasterxml.jackson.core</groupId> 93 <artifactId>jackson-core</artifactId> 94 <version>2.9.8</version> 95 </dependency> 96 <dependency> 97 <groupId>com.fasterxml.jackson.core</groupId> 98 <artifactId>jackson-annotations</artifactId> 99 <version>2.9.8</version> 100 </dependency> 101 <dependency> 102 <groupId>com.fasterxml.jackson.core</groupId> 103 <artifactId>jackson-databind</artifactId> 104 <version>2.9.8</version> 105 </dependency> 106 <!--数据库连接池的jar包--> 107 108 <dependency> 109 <groupId>commons-dbcp</groupId> 110 <artifactId>commons-dbcp</artifactId> 111 <version>1.4</version> 112 </dependency> 113 114 <!--jstl的jar包--> 115 <dependency> 116 <groupId>jstl</groupId> 117 <artifactId>jstl</artifactId> 118 <version>1.2</version> 119 </dependency> 120 121 </dependencies> 122 123 124 <build> 125 <resources> 126 <!--指定src main java下所有的目录下的xml文件都编译--> 127 <resource> 128 <directory>src/main/java</directory> 129 <includes> 130 <include>**/*.xml</include> 131 </includes> 132 </resource> 133 </resources> 134 </build> 135 136 </project>
二、准备数据库表
三、准备pojo(java类)也就是实体类,对应数据库
四、准备jdbc.properties文件
1 mysql: 2 driver=com.mysql.jdbc.Driver 3 url=jdbc:mysql://localhost:3306/ssm?characterEncoding=utf-8 4 username=root 5 password=admin 6 7 oracle: 8 driver=oracle.jdbc.driver.OracleDriver 9 url=jdbc:oracle:thin:@localhost:1521:orcl 10 user=scott 11 password=tiger
五、applicationContext.xml配置文件(也就是spring主配置文件)
1 <?xml version="1.0" encoding="UTF-8"?> 2 <beans xmlns="http://www.springframework.org/schema/beans" 3 xmlns:xsi="http://www.w3.org/2001/XMLSchema-instance" 4 xmlns:context="http://www.springframework.org/schema/context" xmlns:tx="http://www.springframework.org/schema/tx" 5 xmlns:aop="http://www.springframework.org/schema/aop" 6 7 xsi:schemaLocation="http://www.springframework.org/schema/beans http://www.springframework.org/schema/beans/spring-beans.xsd http://www.springframework.org/schema/context http://www.springframework.org/schema/context/spring-context.xsd http://www.springframework.org/schema/tx http://www.springframework.org/schema/tx/spring-tx.xsd http://www.springframework.org/schema/aop http://www.springframework.org/schema/aop/spring-aop.xsd"> 8 9 <!--第一步,扫描service --> 10 <context:component-scan base-package="com.aaa.ssm.service"></context:component-scan> 11 <!--第二步,加载jdbc.properties--> 12 <context:property-placeholder location="classpath:jdbc.properties"></context:property-placeholder> 13 <!--第三步,创建dbcp数据源连接池--> 14 <bean id="dataSource" class="org.apache.commons.dbcp.BasicDataSource"> 15 <property name="driverClassName" value="${driver}"></property> 16 <property name="url" value="${url}"></property> 17 <property name="username" value="${user}"></property> 18 <property name="password" value="${password}"></property> 19 </bean> 20 <!--第四步,创建mybatis的工厂类对象--> 21 <bean class="org.mybatis.spring.SqlSessionFactoryBean"> 22 <!--指定数据源--> 23 <property name="dataSource" ref="dataSource"></property> 24 <!--加载mybatis的映射文件 在value中可以使用*号通配符--> 25 <property name="mapperLocations" value="classpath:com/aaa/ssm/dao/*.xml"></property> 26 </bean> 27 <!--第五步,在spring 的工厂中生成dao接口的实现类对象 --> 28 <bean class="org.mybatis.spring.mapper.MapperScannerConfigurer"> 29 <!--指定要扫描哪个包下面所有的dao接口--> 30 <property name="basePackage" value="com.aaa.ssm.dao"></property> 31 </bean> 32 <!--第六步,创建spring的事物管理器--> 33 <bean id="transactionManager" class="org.springframework.jdbc.datasource.DataSourceTransactionManager"> 34 <property name="dataSource" ref="dataSource"></property> 35 </bean> 36 <!--第七步,声明以注解的方式配置声明式事物--> 37 <tx:annotation-driven transaction-manager="transactionManager" ></tx:annotation-driven> 38 39 <!--第八步,配置事物-通知 --> 40 <tx:advice id="txAdvice" transaction-manager="transactionManager"> 41 <tx:attributes> 42 <tx:method name="add*" propagation="REQUIRED"/> 43 <tx:method name="delete*" propagation="REQUIRED"/> 44 <tx:method name="find*" propagation="REQUIRED"/> 45 <tx:method name="edit*" propagation="REQUIRED"/> 46 </tx:attributes> 47 </tx:advice> 48 <!-- 第九步,配置事物-切面 --> 49 <aop:config> 50 <aop:advisor advice-ref="txAdvice" pointcut="execution(* com.aaa.ssm.service.*.*(..))"/> 51 </aop:config> 52 53 </beans>
步骤:
1、扫描service
2、加载jdbc
3、创建dbcp数据源连接池
4、创建mybatis的工厂类对象
5、在spring的工厂中生成dao接口的实现类对象
6、创建spring的事务管理器
7、声明以注解的方式配置声明式事务
8、配置事务通知
9、配置aop
六、spring-mvc配置文件
1 <?xml version="1.0" encoding="UTF-8"?> 2 <beans xmlns="http://www.springframework.org/schema/beans" 3 xmlns:xsi="http://www.w3.org/2001/XMLSchema-instance" 4 xmlns:context="http://www.springframework.org/schema/context" 5 xmlns:mvc="http://www.springframework.org/schema/mvc" 6 xsi:schemaLocation="http://www.springframework.org/schema/beans 7 http://www.springframework.org/schema/beans/spring-beans.xsd 8 http://www.springframework.org/schema/context 9 http://www.springframework.org/schema/context/spring-context.xsd 10 http://www.springframework.org/schema/mvc 11 http://www.springframework.org/schema/mvc/spring-mvc.xsd"> 12 <!-- 配置controller扫描--> 13 <context:component-scan base-package="com.aaa.ssm.controller"></context:component-scan> 14 <!-- 配置注解驱动 --> 15 <mvc:annotation-driven></mvc:annotation-driven> 16 <!-- 配置视图解析器 --> 17 <bean class="org.springframework.web.servlet.view.InternalResourceViewResolver"> 18 <property name="prefix" value="/WEB-INF/jsp/"></property> 19 <property name="suffix" value=".jsp"></property> 20 </bean> 21 </beans>
步骤:
1:、配置controller扫描
2、配置注解驱动
3、配置视图解析器
七、dao层以及mapper实现
注:在applicationContext.xml中配置了自动扫描mapper,所有路径一定要保持一致,命名也是一样。
八、service层
根据所需要的业务逻辑来调用dao层的接口来实现业务处理。
九、controller层
控制层调用service来实现业务处理并且返回相对应的jsp页面以及重定向等。(注:jsp页面的路径问题,在spring-mvc配置文件中配置了视图解析的前缀和后缀,注意)
十、写自己所需要的jsp
这个并不是必须在最后写的,也可以先写一些会用到的,也可以在写controller的过程中,需要哪个页面然后就写哪个就好。
十一、最后部署到服务器上,注意jar包也要同时部署到服务器。
