如何开始:
整个项目建立好了的结构在这里可以看到:
https://github.com/michaelssss/MealControlSystem
首先这是基于IDEA的一个示例(我表示Eclipse实在不讨喜,Eclispse自己也发现这个问题已经有新的产品了)。
我们选择通过IDEA的模板新建一个Maven工程
大概的结构会如上图所示,Maven的Dependecies如下
<?xml version="1.0" encoding="UTF-8"?> <project xmlns:xsi="http://www.w3.org/2001/XMLSchema-instance" xmlns="http://maven.apache.org/POM/4.0.0" xsi:schemaLocation="http://maven.apache.org/POM/4.0.0 http://maven.apache.org/xsd/maven-4.0.0.xsd"> <modelVersion>4.0.0</modelVersion> <groupId>MyWebClient</groupId> <artifactId>MealControlSystem</artifactId> <version>0.0.1</version> <packaging>war</packaging> <properties> <project.build.sourceEncoding>UTF-8</project.build.sourceEncoding> <atmosphere-version>2.4.2</atmosphere-version> <spring-version>4.2.3.RELEASE</spring-version> </properties> <dependencies> <dependency> <groupId>junit</groupId> <artifactId>junit</artifactId> <version>4.12</version> <scope>test</scope> </dependency> <!-- Spring --> <dependency> <groupId>javax.inject</groupId> <artifactId>javax.inject</artifactId> <version>1</version> </dependency> <dependency> <groupId>org.springframework</groupId> <artifactId>spring-core</artifactId> <version>{spring-version}</version> </dependency> <dependency> <groupId>org.springframework</groupId> <artifactId>spring-web</artifactId> <version>{spring-version}</version> </dependency> <dependency> <groupId>org.springframework</groupId> <artifactId>spring-webmvc</artifactId> <version>{spring-version}</version> </dependency> <dependency> <groupId>org.springframework</groupId> <artifactId>spring-tx</artifactId> <version>{spring-version}</version> </dependency> <dependency> <groupId>org.springframework</groupId> <artifactId>spring-orm</artifactId> <version>{spring-version}</version> </dependency> <dependency> <groupId>org.springframework</groupId> <artifactId>spring-aop</artifactId> <version>{spring-version}</version> </dependency> <dependency> <groupId>com.fasterxml.jackson.core</groupId> <artifactId>jackson-core</artifactId> <version>2.7.2</version> </dependency> <dependency> <groupId>com.fasterxml.jackson.core</groupId> <artifactId>jackson-databind</artifactId> <version>2.7.2</version> </dependency> <dependency> <groupId>com.fasterxml.jackson.core</groupId> <artifactId>jackson-annotations</artifactId> <version>2.7.2</version> </dependency> <dependency> <groupId>org.hibernate</groupId> <artifactId>hibernate-core</artifactId> <version>5.0.7.Final</version> </dependency> <!-- for JPA, use hibernate-entitymanager instead of hibernate-core --> <dependency> <groupId>org.hibernate</groupId> <artifactId>hibernate-entitymanager</artifactId> <version>5.0.7.Final</version> </dependency> <!-- optional --> <dependency> <groupId>org.hibernate</groupId> <artifactId>hibernate-osgi</artifactId> <version>5.0.7.Final</version> </dependency> <dependency> <groupId>org.hibernate</groupId> <artifactId>hibernate-envers</artifactId> <version>5.0.7.Final</version> </dependency> <dependency> <groupId>org.hibernate</groupId> <artifactId>hibernate-c3p0</artifactId> <version>5.0.7.Final</version> </dependency> <dependency> <groupId>org.hibernate</groupId> <artifactId>hibernate-proxool</artifactId> <version>5.0.7.Final</version> </dependency> <dependency> <groupId>org.hibernate</groupId> <artifactId>hibernate-infinispan</artifactId> <version>5.0.7.Final</version> </dependency> <dependency> <groupId>org.hibernate</groupId> <artifactId>hibernate-ehcache</artifactId> <version>5.0.7.Final</version> </dependency> <dependency> <groupId>mysql</groupId> <artifactId>mysql-connector-java</artifactId> <version>5.1.38</version> </dependency> <dependency> <groupId>javax.mail</groupId> <artifactId>javax.mail-api</artifactId> <version>1.5.4</version> </dependency> <dependency> <groupId>javax.activation</groupId> <artifactId>activation</artifactId> <version>1.1</version> </dependency> <dependency> <groupId>javax.servlet</groupId> <artifactId>javax.servlet-api</artifactId> <version>3.1.0</version> <scope>provided</scope> </dependency> <dependency> <groupId>javax.servlet</groupId> <artifactId>jsp-api</artifactId> <version>2.0</version> <scope>provided</scope> </dependency> <dependency> <groupId>org.aspectj</groupId> <artifactId>aspectjrt</artifactId> <version>1.8.8</version> </dependency> <dependency> <groupId>org.aspectj</groupId> <artifactId>aspectjweaver</artifactId> <version>1.8.8</version> </dependency> </dependencies> <build> <plugins> <plugin> <groupId>org.codehaus.cargo</groupId> <artifactId>cargo-maven2-plugin</artifactId> <version>1.4.18</version> <configuration> <container> <containerId>wildfly10x</containerId> <home>/home/michaelssss/server/wildfly-10.0.0.Final</home> </container> <configuration> <type>standalone</type> <home>${project.build.directory}/wildfly-10.0.0.Final</home> </configuration> </configuration> </plugin> <plugin> <groupId>org.apache.maven.plugins</groupId> <artifactId>maven-compiler-plugin</artifactId> <configuration> <source>1.8</source> <target>1.8</target> </configuration> </plugin> </plugins> </build> </project>
具体需要的包是,Spring全家桶,Hibernate全家桶(用全家桶是懒得找缺少包,全包括肯定没错,但是在空间要求紧张的时候就必须要精确只有必须要用的包才能包括)。
EJB容器我们采用的是WildFly10版本,同时配置好数据源(注意引入相应的数据源的驱动)
在webapp下添加web.xml 填入以下代码
<?xml version="1.0" encoding="UTF-8"?> <web-app xmlns:xsi="http://www.w3.org/2001/XMLSchema-instance" xmlns="http://xmlns.jcp.org/xml/ns/javaee" xsi:schemaLocation="http://xmlns.jcp.org/xml/ns/javaee http://xmlns.jcp.org/xml/ns/javaee/web-app_3_1.xsd" version="3.1"> <display-name>Spring Web MVC Application</display-name> <servlet> <servlet-name>mvc-dispatcher</servlet-name> <servlet-class> org.springframework.web.servlet.DispatcherServlet </servlet-class> <init-param> <param-name>contextConfigLocation</param-name> <param-value> /WEB-INF/applicationContext.xml </param-value> </init-param> <load-on-startup>1</load-on-startup> </servlet> <listener> <listener-class> org.springframework.web.context.ContextLoaderListener </listener-class> </listener> <context-param> <param-name>contextConfigLocation</param-name> <param-value>/WEB-INF/applicationContext.xml</param-value> </context-param> <servlet-mapping> <servlet-name>mvc-dispatcher</servlet-name> <url-pattern>/</url-pattern> </servlet-mapping> <servlet> <servlet-name>MyServlet</servlet-name> <servlet-class>MyMealControlSystem.BackGroundService.MyServlet</servlet-class> <load-on-startup>2</load-on-startup> </servlet> <!-- 修改编码 --> <filter> <filter-name>projectEncoding</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>projectEncoding</filter-name> <url-pattern>/*</url-pattern> </filter-mapping> </web-app>
web.xml的具体意义就是引入一个Servlet服务,具体到这里就是SpringMVC的Listener做响应处理。有一点注意的是要指定application.xml的位置,不然就会找不到
其他的代码看注释
在同级目录下加入application.xml,提供Spring与hibernate的设置:
<?xml version="1.0" encoding="UTF-8"?> <beans xmlns:xsi="http://www.w3.org/2001/XMLSchema-instance" xmlns:context="http://www.springframework.org/schema/context" xmlns:aop="http://www.springframework.org/schema/aop" xmlns:mvc="http://www.springframework.org/schema/mvc" xmlns="http://www.springframework.org/schema/beans" 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/aop http://www.springframework.org/schema/aop/spring-aop.xsd http://www.springframework.org/schema/mvc http://www.springframework.org/schema/mvc/spring-mvc.xsd"> <context:annotation-config/> <mvc:annotation-driven/> <bean id="session" class="MyMealControlSystem.BackGroundService.BaseService.Service"> <property name="sessionFactory" ref="sessionFactory"/> </bean> <context:component-scan base-package="MyMealControlSystem.OutGroundServices"/> <context:component-scan base-package="MyMealControlSystem.Utils"/> <context:component-scan base-package="MyMealControlSystem.AOPService"/> <bean id="dataSource" class="org.springframework.jndi.JndiObjectFactoryBean"> <property name="jndiName"> <value>java:/Meal</value> </property> <property name="cache" value="false"/> <property name="proxyInterface" value="javax.sql.DataSource"/> </bean> <bean id="sessionFactory" class="org.springframework.orm.hibernate5.LocalSessionFactoryBean"> <property name="dataSource" ref="dataSource"/> <property name="packagesToScan"> <value>MyMealControlSystem.OutGroundServices.POJO</value> </property> <property name="hibernateProperties"> <props> <prop key="hibernate.pool_size">3</prop> <prop key="hbm2ddl.auto">update</prop> <prop key="hibernate.dialect">org.hibernate.dialect.MySQLDialect</prop> <prop key="hibernate.show_sql">true</prop> <prop key="hibernate.current_session_context_class">thread</prop> <prop key="format_sql">false</prop> <prop key="hibernate.connection.url">jdbc:mysql://localhost:3306</prop> <prop key="hibernate.connection.driver_class">com.mysql.jdbc.Driver</prop> </props> </property> </bean> <bean id="transactionManager" class="org.springframework.orm.hibernate5.HibernateTransactionManager"> <property name="sessionFactory" ref="sessionFactory"/> </bean> <bean class="org.springframework.web.servlet.view.InternalResourceViewResolver"> <property name="prefix" value="JSP/"/> <property name="suffix" value=".jsp"/> </bean> <bean id="identifyUser" class="MyMealControlSystem.AOPService.identifyUser"> </bean> <aop:aspectj-autoproxy proxy-target-class="true"> </aop:aspectj-autoproxy> </beans>
解释一下,这里采用自动扫描的方式来配置SpringMVC和Hibernate。Hibernate采用EntityManager的方式管理尽量减少Xml的设置减少出错。
接下来。。不想写了。。就是普通的添加SpringMVC的Controller,生成POJO实体BLABLABLABLA,这个网上一堆堆就不说了,主要想记录的就是如何在采用注解的方式配置的Hibernate如何和Spring整合。具体接下来的设计放到之后的文章,总之,通过上述的步骤就能够建立一个SH的Javaweb的包了。
