项目的目录结构
第一步:导入依赖
<?xml version="1.0" encoding="UTF-8"?> <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"> <modelVersion>4.0.0</modelVersion> <groupId>com.yjc</groupId> <artifactId>InvoicingSystem</artifactId> <version>1.0-SNAPSHOT</version> <packaging>war</packaging> <name>InvoicingSystem Maven Webapp</name> <!-- FIXME change it to the project's website --> <url>http://www.example.com</url> <properties> <project.build.sourceEncoding>UTF-8</project.build.sourceEncoding> <maven.compiler.source>1.7</maven.compiler.source> <maven.compiler.target>1.7</maven.compiler.target> </properties> <dependencies> <dependency> <groupId>junit</groupId> <artifactId>junit</artifactId> <version>4.11</version> <scope>test</scope> </dependency> <!--日志--> <dependency> <groupId>log4j</groupId> <artifactId>log4j</artifactId> <version>1.2.17</version> </dependency> <dependency> <groupId>org.springframework</groupId> <artifactId>spring-webmvc</artifactId> <version>4.2.0.RELEASE</version> </dependency> <dependency> <groupId>org.springframework</groupId> <artifactId>spring-web</artifactId> <version>4.2.0.RELEASE</version> </dependency> <!--MyBatis和Spring的整合包 由MyBatis提供--> <dependency> <groupId>org.mybatis</groupId> <artifactId>mybatis-spring</artifactId> <version>1.3.0</version> </dependency> <!--MyBatis的核心jar文件--> <dependency> <groupId>org.mybatis</groupId> <artifactId>mybatis</artifactId> <version>3.4.1</version> </dependency> <dependency> <groupId>mysql</groupId> <artifactId>mysql-connector-java</artifactId> <version>5.1.32</version> </dependency> <dependency> <groupId>org.springframework</groupId> <artifactId>spring-jdbc</artifactId> <version>4.2.0.RELEASE</version> </dependency> <dependency> <groupId>com.fasterxml.jackson.core</groupId> <artifactId>jackson-core</artifactId> <version>2.2.1</version> </dependency> <dependency> <groupId>com.fasterxml.jackson.core</groupId> <artifactId>jackson-annotations</artifactId> <version>2.2.1</version> </dependency> <dependency> <groupId>com.fasterxml.jackson.core</groupId> <artifactId>jackson-databind</artifactId> <version>2.2.1</version> </dependency> <!--生成实体类--> <dependency> <groupId>org.mybatis.generator</groupId> <artifactId>mybatis-generator-core</artifactId> <version>1.3.7</version> </dependency> <!--分页--> <dependency> <groupId>com.github.pagehelper</groupId> <artifactId>pagehelper</artifactId> <version>4.1.0</version> </dependency> <dependency> <groupId>javax.servlet</groupId> <artifactId>javax.servlet-api</artifactId> <version>3.1.0</version> </dependency> </dependencies> <build> <!--扫描配置文件--> <resources> <resource> <directory>src/main/java</directory> <includes> <include>**/*.xml</include> </includes> </resource> </resources> <finalName>InvoicingSystem</finalName> <pluginManagement><!-- lock down plugins versions to avoid using Maven defaults (may be moved to parent pom) --> <plugins> <plugin> <artifactId>maven-clean-plugin</artifactId> <version>3.1.0</version> </plugin> <!-- see http://maven.apache.org/ref/current/maven-core/default-bindings.html#Plugin_bindings_for_war_packaging --> <plugin> <artifactId>maven-resources-plugin</artifactId> <version>3.0.2</version> </plugin> <plugin> <artifactId>maven-compiler-plugin</artifactId> <version>3.8.0</version> </plugin> <plugin> <artifactId>maven-surefire-plugin</artifactId> <version>2.22.1</version> </plugin> <plugin> <artifactId>maven-war-plugin</artifactId> <version>3.2.2</version> </plugin> <plugin> <artifactId>maven-install-plugin</artifactId> <version>2.5.2</version> </plugin> <plugin> <artifactId>maven-deploy-plugin</artifactId> <version>2.8.2</version> </plugin> <!--生成实体类--> <plugin> <groupId>org.mybatis.generator</groupId> <artifactId>mybatis-generator-maven-plugin</artifactId> <version>1.3.2</version> </plugin> </plugins> </pluginManagement> </build> </project>
第二步:mybatis核心配置文件
<?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> <properties resource="jdbc.properties"></properties> <settings> <setting name="logImpl" value="LOG4J"/> <setting name="autoMappingBehavior" value="FULL"/> <!--开启二级缓存--> <!-- <setting name="cacheEnabled" value="true"></setting>--> </settings> <typeAliases> <package name="com.yjc.entity"/> </typeAliases> <!--使用pageHelp的插件--> <plugins> <plugin interceptor="com.github.pagehelper.PageHelper"> </plugin> </plugins> <!--管理小配置文件--> <mappers> <package name="com.yjc.dao"/> </mappers> </configuration>
第三步:Spring核心配置文件
<?xml version="1.0" encoding="UTF-8"?> <beans xmlns="http://www.springframework.org/schema/beans" xmlns:xsi="http://www.w3.org/2001/XMLSchema-instance" xmlns:tx="http://www.springframework.org/schema/tx" xmlns:aop="http://www.springframework.org/schema/aop" xmlns:context="http://www.springframework.org/schema/context" xmlns:mvc="http://www.springframework.org/schema/mvc" xsi:schemaLocation="http://www.springframework.org/schema/beans http://www.springframework.org/schema/beans/spring-beans.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 http://www.springframework.org/schema/context http://www.springframework.org/schema/context/spring-context.xsd http://www.springframework.org/schema/mvc http://www.springframework.org/schema/mvc/spring-mvc.xsd"> <!-- 导入数据库连接文件--> <bean class="org.springframework.beans.factory.config.PropertyPlaceholderConfigurer"> <property name="ignoreUnresolvablePlaceholders" value="true" /> <property name="location" value="classpath:jdbc.properties"/> </bean> <!--配置数据源--> <bean id="dataSource" class="org.springframework.jdbc.datasource.DriverManagerDataSource"> <property name="driverClassName" value="${jdbc.driver}"/> <property name="url" value="${jdbc.url}"/> <property name="password" value="${jdbc.password}"/> <property name="username" value="${jdbc.user}"/> </bean> <!--配置MyBatis的核心对象SqlSessionFactoryBean--> <bean id="sqlSessionFactory" class="org.mybatis.spring.SqlSessionFactoryBean"> <property name="dataSource" ref="dataSource"/> <!--可指向MyBatis的核心配置文件--> <property name="configLocation" value="classpath:mybatis-config.xml"></property> </bean> <!--创建包扫描器（借助dao接口实现动态代理）--> <bean class="org.mybatis.spring.mapper.MapperScannerConfigurer"> <property name="basePackage" value="com.yjc.dao"/> </bean> <!--将Service实现类对象声明到Spring容器中--> <!--spring中的隐式注入--> <!--事务配置--> <bean id="transactionManager" class="org.springframework.jdbc.datasource.DataSourceTransactionManager"> <property name="dataSource" ref="dataSource"/> </bean> <!-- <tx:advice transaction-manager="transactionManager" id="txAdvice"> <tx:attributes> <tx:method name="getAll" isolation="READ_COMMITTED" propagation="REQUIRED"/> </tx:attributes> </tx:advice> <aop:config> <aop:advisor advice-ref="txAdvice" pointcut="execution(* com.yjc.service.*.*(..))"></aop:advisor> </aop:config>--> <!--扫描包下的注解--> <context:component-scan base-package="com.yjc"/> <context:annotation-config/> <tx:annotation-driven/> <mvc:annotation-driven/> </beans>
第四步:Spring-mvc核心配置文件
<?xml version="1.0" encoding="UTF-8"?> <!--根节点是我们的beans节点--> <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" xmlns:mvc="http://www.springframework.org/schema/mvc" 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/mvc http://www.springframework.org/schema/mvc/spring-mvc.xsd"> <!-- 配置包扫描器，扫描com.cmy下及其子包下注解 --> <context:component-scan base-package="com.yjc"/> <!-- 开启Spring MVC 注解配置的支持 --> <mvc:annotation-driven /> <!-- 配置视图解析器,设置前缀和后缀，自动拼接 --> <bean class="org.springframework.web.servlet.view.InternalResourceViewResolver"> <!-- 前缀 --> <property name="prefix" value="/jsp/" /> <!-- 后缀 --> <property name="suffix" value=".jsp" /> </bean> <!--解决拦截静态资源问题--> <mvc:default-servlet-handler/> </beans>
第五步:数据库配置文件
jdbc.driver=com.mysql.jdbc.Driver
jdbc.url=jdbc:mysql://localhost:3306/invoicingsystem
jdbc.user=用户名
jdbc.password=密码
第六步:配置Web.xml
<?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_3_1.xsd" version="3.1"> <!--配置SpringMVC的核心控制器DispatcherServlet--> <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-mvc.xml</param-value> </init-param> </servlet> <!--Spring和MyBatis整合的核心配置--> <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-mapping> <servlet-name>SpringMVC</servlet-name> <!--设置映射路径，/代表所有的请求都会被核心控制器映射到对应的Controller中--> <url-pattern>/</url-pattern> </servlet-mapping> <!-- <servlet-mapping> <servlet-name>SpringMVC</servlet-name> <url-pattern>*.jpg</url-pattern> </servlet-mapping>--> <!--编码过滤器--> <filter> <filter-name>characterEncodingFilter</filter-name> <filter-class>org.springframework.web.filter.CharacterEncodingFilter</filter-class> <!--初始化参数--> <init-param> <param-name>encoding</param-name> <param-value>UTF-8</param-value> </init-param> </filter> <filter-mapping> <filter-name>characterEncodingFilter</filter-name> <url-pattern>/*</url-pattern> </filter-mapping> <error-page> <error-code>404</error-code> <!--(里面写你的页面所存放的路径)--> <location>/jsp/404.jsp</location> </error-page> </web-app>
第七步:将所有将要使用的Dao,ServiceImpl,Controller使用注解方式注入到Spring容器中,同时使这三层逐层调用,最后就可以从前台访问所声明的Controller了
