首先我们要构建一个企业级的权限管理项目的话,首先肯定是创建我们的项目:
然后第一步:在我们的pom文件中加入相关的依赖,依赖如下:
<dependencies> <dependency> <groupId>junit</groupId> <artifactId>junit</artifactId> <version>4.11</version> <scope>test</scope> </dependency> <dependency> <groupId>org.springframework</groupId> <artifactId>spring-beans</artifactId> <version>${springframework.version}</version> </dependency> <dependency> <groupId>org.springframework</groupId> <artifactId>spring-context</artifactId> <version>${springframework.version}</version> </dependency> <!--Spring MVC + Spring web--> <dependency> <groupId>org.springframework</groupId> <artifactId>spring-web</artifactId> <version>${springframework.version}</version> </dependency> <dependency> <groupId>org.springframework</groupId> <artifactId>spring-webmvc</artifactId> <version>${springframework.version}</version> </dependency> <dependency> <groupId>org.springframework</groupId> <artifactId>spring-jdbc</artifactId> <version>${springframework.version}</version> </dependency> <!-- Mybatis --> <dependency> <groupId>org.mybatis</groupId> <artifactId>mybatis</artifactId> <version>3.5.1</version> </dependency> <dependency> <groupId>org.mybatis</groupId> <artifactId>mybatis-spring</artifactId> <version>2.0.1</version> </dependency> <!-- druid --> <dependency> <groupId>com.alibaba</groupId> <artifactId>druid</artifactId> <version>1.0.20</version> </dependency> <!-- mysql --> <dependency> <groupId>mysql</groupId> <artifactId>mysql-connector-java</artifactId> <version>5.1.47</version> </dependency> <!-- lombok --> <dependency> <groupId>org.projectlombok</groupId> <artifactId>lombok</artifactId> <version>1.18.10</version> </dependency> <!-- jackson --> <dependency> <groupId>com.fasterxml.jackson.datatype</groupId> <artifactId>jackson-datatype-guava</artifactId> <version>2.5.3</version> </dependency> <!-- logback --> <dependency> <groupId>org.projectlombok</groupId> <artifactId>lombok</artifactId> <version>1.18.10</version> </dependency> <dependency> <groupId>ch.qos.logback</groupId> <artifactId>logback-core</artifactId> <version>1.2.3</version> </dependency> <dependency> <groupId>ch.qos.logback</groupId> <artifactId>logback-classic</artifactId> <version>1.2.3</version> </dependency> <dependency> <groupId>org.slf4j</groupId> <artifactId>slf4j-api</artifactId> <version>1.7.29</version> </dependency> </dependencies>
在这些依赖里面最核心的是我们的Spring MVC+Spring Web的依赖,然后Mybatis,MySql,druid,lombok,jackson的依赖,然后还有我们的日志logback依赖
第二步:导入完这些依赖后我们要开始编写我们的一个配置文件:
首先是在我们的WEB-INF下面的web.xml添加如下代码:
<!DOCTYPE web-app PUBLIC "-//Sun Microsystems, Inc.//DTD Web Application 2.3//EN" "http://java.sun.com/dtd/web-app_2_3.dtd" > <web-app> <display-name>Archetype Created Web Application</display-name> <listener> <listener-class>org.springframework.web.context.ContextLoaderListener</listener-class> </listener> <!-- Spring beans 配置文件所在目录 --> <context-param> <param-name>contextConfigLocation</param-name> <param-value>classpath:applicationContext.xml</param-value> </context-param> <!-- spring mvc 配置 --> <servlet> <servlet-name>spring</servlet-name> <servlet-class>org.springframework.web.servlet.DispatcherServlet</servlet-class> </servlet> <servlet-mapping> <servlet-name>spring</servlet-name> <url-pattern>/</url-pattern> </servlet-mapping> <!-- Encoding --> <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> <!-- druid --> <servlet> <servlet-name>DruidStatServlet</servlet-name> <servlet-class>com.alibaba.druid.support.http.StatViewServlet</servlet-class> <init-param> <param-name>loginUsername</param-name> <param-value>druid</param-value> </init-param> <init-param> <param-name>loginPassword</param-name> <param-value>druid</param-value> </init-param> </servlet> <servlet-mapping> <servlet-name>DruidStatServlet</servlet-name> <url-pattern>/sys/druid/*</url-pattern> </servlet-mapping> <filter> <filter-name>DruidWebStatFilter</filter-name> <filter-class>com.alibaba.druid.support.http.WebStatFilter</filter-class> <init-param> <param-name>exclusions</param-name> <param-value>*.js,*.css,*.jpg,*.png,*.ico,*.gif,/sys/druid/*</param-value> </init-param> </filter> <filter-mapping> <filter-name>DruidWebStatFilter</filter-name> <url-pattern>/*</url-pattern> </filter-mapping> <welcome-file-list> <welcome-file>index.jsp</welcome-file> </welcome-file-list> </web-app>
在我们的web.xml中有一段classpath:applicationContext.xml
这个的话是我们Spring beans配置文件所在的一个目录,所以我们得去resources下面创建一个applicationContext.xml
然后applicationContext.xml里面的代码如下:
<?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" xsi:schemaLocation="http://www.springframework.org/schema/beans http://www.springframework.org/schema/beans/spring-beans.xsd http://www.alibaba.com/schema/stat http://www.alibaba.com/schema/stat.xsd http://www.springframework.org/schema/mvc http://www.springframework.org/schema/mvc/spring-mvc.xsd http://www.springframework.org/schema/tx http://www.springframework.org/schema/tx/spring-tx.xsd"> <bean id="propertyConfigurer" class="org.springframework.beans.factory.config.PropertyPlaceholderConfigurer"> <property name="ignoreUnresolvablePlaceholders" value="true"/> <property name="locations"> <list> <value>classpath:settings.properties</value> </list> </property> </bean> <bean id="dataSource" class="com.alibaba.druid.pool.DruidDataSource" init-method="init" destroy-method="close"> <property name="driverClassName" value="${db.driverClassName}" /> <property name="url" value="${db.url}" /> <property name="username" value="${db.username}" /> <property name="password" value="${db.password}" /> <property name="initialSize" value="3" /> <property name="minIdle" value="3" /> <property name="maxActive" value="20" /> <property name="maxWait" value="60000" /> <property name="filters" value="stat,wall" /> </bean> <bean id="sqlSessionFactory" class="org.mybatis.spring.SqlSessionFactoryBean"> <property name="configLocation" value="classpath:mybatis-config.xml"/> <property name="dataSource" ref="dataSource"/> <property name="mapperLocations" value="classpath:mapper/*.xml"/> </bean> <bean class="org.mybatis.spring.mapper.MapperScannerConfigurer"> <property name="basePackage" value="cn.oyc.dao"/> <property name="sqlSessionFactoryBeanName" value="sqlSessionFactory"/> </bean> <!-- tx --> <bean id="transactionManager" class="org.springframework.jdbc.datasource.DataSourceTransactionManager"> <property name="dataSource" ref="dataSource" /> </bean> <tx:annotation-driven transaction-manager="transactionManager"/> <!-- druid --> <bean id="stat-filter" class="com.alibaba.druid.filter.stat.StatFilter"> <property name="slowSqlMillis" value="3000" /> <property name="logSlowSql" value="true" /> <property name="mergeSql" value="true" /> </bean> <bean id="wall-filter" class="com.alibaba.druid.wall.WallFilter"> <property name="dbType" value="mysql" /> </bean> </beans>
切记自己所配置的文件的某些路径是否正常
由于我们的applicationContext.xml里有编写我们数据库的一个常量,所以我们在编写一个settings.properties配置文件
内容如下:
db.driverClassName=com.mysql.jdbc.Driver db.url=jdbc:mysql://localhost:3306/diction db.username=root db.password=root
这个主要方便我们数据库的一个连接修改,避免在很多配置文件中查找我们数据库的驱动路径等
然后在编写mybatis-config.xml,代码如下:
<?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> <settings> <setting name="safeRowBoundsEnabled" value="true"/> <setting name="cacheEnabled" value="false" /> <setting name="useGeneratedKeys" value="true" /> </settings> </configuration>
在编写我们的一个logback.xml日志的配置,代码如下:
<?xml version="1.0" encoding="UTF-8"?> <configuration scan="true" sacnPeriod="60 seconds"> <appender name="STDOUT" calss="ch.qos.logback.core.ConsoleAppender"> <encoder> <pattern>%d{yyyy-MM-dd HH:mm:ss.SSS} [%thread] %-5level %logger - %msg%n</pattern> <!-- 百分号d表示日期的意思 --> </encoder> </appender> <root level="INFO"> <appender-ref ref="STDOUT"/> </root> </configuration>
然后最后编写我们的spring-servlet.xml,代码如下:
<?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: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"> <context:annotation-config /> <!-- 启动注解驱动的spring mvc 功能 --> <mvc:annotation-driven/> <!-- 启动包扫描功能 --> <context:component-scan base-package="cn.oyc.controller"/> <context:component-scan base-package="cn.oyc.service"/> <bean class="org.springframework.web.servlet.view.BeanNameViewResolver" /> <bean id="jsonView" class="org.springframework.web.servlet.view.json.MappingJackson2JsonView" /> <bean class="org.springframework.web.servlet.view.InternalResourceViewResolver"> <property name="prefix" value="/WEB-INF/views/" /> <property name="suffix" value=".jsp" /> </bean> </beans>
