SpringMvc 整合mybatis项目搭建
1.使用idea创建maven项目
2.在项目src目录下 添加java文件夹 并设置类型为sources,添加resource文件夹 设置为resources
4.修改pom文件 添加引用
<?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.itstudy</groupId> <artifactId>myweb</artifactId> <version>1.0-SNAPSHOT</version> <packaging>war</packaging> <name>myweb Maven Webapp</name> <url>http://www.example.com</url> <properties> <project.build.sourceEncoding>UTF-8</project.build.sourceEncoding> <maven.compiler.source>1.8</maven.compiler.source> <maven.compiler.target>1.8</maven.compiler.target> </properties> <dependencies> <dependency> <groupId>junit</groupId> <artifactId>junit</artifactId> <version>4.11</version> <scope>test</scope> </dependency> <dependency> <groupId>org.springframework</groupId> <artifactId>spring-core</artifactId> <version>4.3.6.RELEASE</version> </dependency> <dependency> <groupId>org.springframework</groupId> <artifactId>spring-context</artifactId> <version>4.3.6.RELEASE</version> </dependency> <dependency> <groupId>org.springframework</groupId> <artifactId>spring-beans</artifactId> <version>4.3.6.RELEASE</version> </dependency> <dependency> <groupId>org.springframework</groupId> <artifactId>spring-web</artifactId> <version>4.3.6.RELEASE</version> </dependency> <dependency> <groupId>org.springframework</groupId> <artifactId>spring-webmvc</artifactId> <version>4.3.6.RELEASE</version> </dependency> <dependency> <groupId>org.springframework</groupId> <artifactId>spring-jdbc</artifactId> <version>4.3.6.RELEASE</version> </dependency> <dependency> <groupId>org.springframework</groupId> <artifactId>spring-tx</artifactId> <version>4.3.6.RELEASE</version> </dependency> <dependency> <groupId>org.mybatis</groupId> <artifactId>mybatis</artifactId> <version>3.4.1</version> </dependency> <dependency> <groupId>org.mybatis</groupId> <artifactId>mybatis-spring</artifactId> <version>1.3.0</version> </dependency> <dependency> <groupId>mysql</groupId> <artifactId>mysql-connector-java</artifactId> <version>5.1.39</version> </dependency> <dependency> <groupId>com.alibaba</groupId> <artifactId>druid</artifactId> <version>1.1.7</version> </dependency> <dependency> <groupId>javax.servlet</groupId> <artifactId>javax.servlet-api</artifactId> <version>3.0.1</version> <scope>provided</scope> </dependency> <dependency> <groupId>javax.servlet</groupId> <artifactId>jstl</artifactId> <version>1.2</version> </dependency> <dependency> <groupId>taglibs</groupId> <artifactId>standard</artifactId> <version>1.1.2</version> </dependency> </dependencies> <build> <finalName>myweb</finalName> <plugins> <plugin> <groupId>org.apache.tomcat.maven</groupId> <artifactId>tomcat7-maven-plugin</artifactId> <configuration> <port>8080</port> <path>/</path> <uriEncoding>UTF-8</uriEncoding> </configuration> </plugin> </plugins> </build> </project>
5.修改web.xml
<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" metadata-complete="true"> <!-- 如果是用mvn命令生成的xml，需要修改servlet版本为3.1 --> <!-- 配置DispatcherServlet --> <servlet> <servlet-name>springMvc</servlet-name> <servlet-class>org.springframework.web.servlet.DispatcherServlet</servlet-class> <!-- 配置springMVC需要加载的配置文件 spring-dao.xml,spring-service.xml,spring-web.xml Mybatis - > spring -> springmvc --> <init-param> <param-name>contextConfigLocation</param-name> <param-value>classpath:spring-*.xml</param-value> </init-param> </servlet> <servlet-mapping> <servlet-name>springMvc</servlet-name> <!-- 默认匹配所有的请求 --> <url-pattern>/</url-pattern> </servlet-mapping> </web-app>
6.配置mybatis
在resources文件夹中 添加mybatis-config.xml
<?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> <!-- 配置全局属性 --> <settings> <!-- 使用jdbc的getGeneratedKeys获取数据库自增主键值 --> <setting name="useGeneratedKeys" value="true" /> <!-- 使用列别名替换列名 默认:true --> <setting name="useColumnLabel" value="true" /> <!-- 开启驼峰命名转换:Table{create_time} -> Entity{createTime} --> <setting name="mapUnderscoreToCamelCase" value="true" /> </settings> </configuration>
7.配置mybatis-spring
7.1.在resources文件夹中 添加spring-dao.xml
<?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" 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"> <!-- 配置整合mybatis过程 --> <!-- 1.配置数据库相关参数properties的属性：${url} --> <context:property-placeholder location="classpath:jdbc.properties" /> <!-- 2.数据库连接池 --> <bean id="dataSource" class="com.alibaba.druid.pool.DruidDataSource" destroy-method="close"> <!-- 数据库基本信息配置 --> <property name="url" value="${jdbc.url}" /> <property name="username" value="${jdbc.username}" /> <property name="password" value="${jdbc.password}" /> <property name="driverClassName" value="${jdbc.driverClassName}" /> <property name="filters" value="${jdbc.filters}" /> <!-- 最大并发连接数 --> <property name="maxActive" value="${jdbc.maxActive}" /> <!-- 初始化连接数量 --> <property name="initialSize" value="${jdbc.initialSize}" /> <!-- 配置获取连接等待超时的时间 --> <property name="maxWait" value="${jdbc.maxWait}" /> <!-- 最小空闲连接数 --> <property name="minIdle" value="${jdbc.minIdle}" /> <!-- 配置间隔多久才进行一次检测，检测需要关闭的空闲连接，单位是毫秒 --> <property name="timeBetweenEvictionRunsMillis" value="${jdbc.timeBetweenEvictionRunsMillis}" /> <!-- 配置一个连接在池中最小生存的时间，单位是毫秒 --> <property name="minEvictableIdleTimeMillis" value="${jdbc.minEvictableIdleTimeMillis}" /> <property name="validationQuery" value="${jdbc.validationQuery}" /> <property name="testWhileIdle" value="${jdbc.testWhileIdle}" /> <property name="testOnBorrow" value="${jdbc.testOnBorrow}" /> <property name="testOnReturn" value="${jdbc.testOnReturn}" /> <property name="maxOpenPreparedStatements" value="${jdbc.maxOpenPreparedStatements}" /> <!-- 打开removeAbandoned功能 --> <property name="removeAbandoned" value="${jdbc.removeAbandoned}" /> <!-- 1800秒，也就是30分钟 --> <property name="removeAbandonedTimeout" value="${jdbc.removeAbandonedTimeout}" /> <!-- 关闭abanded连接时输出错误日志 --> <property name="logAbandoned" value="${jdbc.logAbandoned}" /> </bean> <!-- 3.配置SqlSessionFactory对象 --> <bean id="sqlSessionFactory" class="org.mybatis.spring.SqlSessionFactoryBean"> <!-- 注入数据库连接池 --> <property name="dataSource" ref="dataSource" /> <!-- 配置MyBaties全局配置文件:mybatis-config.xml --> <property name="configLocation" value="classpath:mybatis-config.xml" /> <!-- 扫描entity包 使用别名 --> <property name="typeAliasesPackage" value="com.soecode.lyf.entity" /> <!-- 扫描sql配置文件:mapper需要的xml文件 --> <property name="mapperLocations" value="classpath:mapper/*.xml" /> </bean> <!-- 4.配置扫描Dao接口包，动态实现Dao接口，注入到spring容器中 --> <bean class="org.mybatis.spring.mapper.MapperScannerConfigurer"> <!-- 注入sqlSessionFactory --> <property name="sqlSessionFactoryBeanName" value="sqlSessionFactory" /> <!-- 给出需要扫描Dao接口包 --> <property name="basePackage" value="com.soecode.lyf.dao" /> </bean> </beans>
7.2在resources文件夹中 添加jdbc.properties
jdbc.url:jdbc:mysql://localhost:3306/dbname
jdbc.driverClassName:com.mysql.jdbc.Driver
jdbc.username:root
jdbc.password:password
jdbc.filters:stat
jdbc.maxActive:20
jdbc.initialSize:1
jdbc.maxWait:60000
jdbc.minIdle:10
jdbc.maxIdle:15
jdbc.timeBetweenEvictionRunsMillis:60000
jdbc.minEvictableIdleTimeMillis:300000
jdbc.validationQuery:SELECT 'x'
jdbc.testWhileIdle:true
jdbc.testOnBorrow:false
jdbc.testOnReturn:false
jdbc.maxOpenPreparedStatements:20
jdbc.removeAbandoned:true
jdbc.removeAbandonedTimeout:1800
jdbc.logAbandoned:true
7.3在resources文件夹中 创建mapper文件夹 并添加相关的mapper文件(以用户表为示例)
UserMapper.xml
<?xml version="1.0" encoding="UTF-8" ?> <!DOCTYPE mapper PUBLIC "-//mybatis.org//DTD Mapper 3.0//EN" "http://mybatis.org/dtd/mybatis-3-mapper.dtd" > <mapper namespace="com.itstudy.dao.UserMapper" > <resultMap id="BaseResultMap" type="com.itstudy.domain.UserInfo" > <id column="id" property="id" jdbcType="BIGINT" /> <result column="name" property="name" jdbcType="VARCHAR" /> <result column="email" property="email" jdbcType="VARCHAR" /> <result column="psncode" property="psncode" jdbcType="VARCHAR" /> <result column="corp_name" property="corpName" jdbcType="VARCHAR" /> <result column="dept_name" property="deptName" jdbcType="VARCHAR" /> <result column="add_time" property="addTime" jdbcType="VARCHAR" /> <result column="remark" property="remark" jdbcType="VARCHAR" /> </resultMap> <insert id="insert" parameterType="com.itstudy.domain.UserInfo" > insert into sys_user (id, name, email,psncode,corp_name,dept_name,add_time,remark) values (#{id,jdbcType=BIGINT}, #{name,jdbcType=VARCHAR}, #{email,jdbcType=VARCHAR}, #{psncode,jdbcType=VARCHAR}, #{corp_name,jdbcType=VARCHAR}, #{dept_name,jdbcType=VARCHAR}, #{add_time,jdbcType=VARCHAR}, #{remark,jdbcType=VARCHAR}) </insert> <update id="update" parameterType="com.itstudy.domain.UserInfo" > update sys_admin set id=#{id,jdbcType=BIGINT}, name = #{name,jdbcType=VARCHAR}, email=#{email,jdbcType=VARCHAR}, psncode=#{psncode,jdbcType=VARCHAR}, corp_name=#{corp_name,jdbcType=VARCHAR}, dept_name=#{dept_name,jdbcType=VARCHAR}, add_time=#{add_time,jdbcType=VARCHAR}, remark=#{remark,jdbcType=VARCHAR} where id = #{id,jdbcType=BIGINT} </update> <delete id="delete" parameterType="int"> delete from sys_admin where id = #{id} </delete> <select id="findByPsncode" parameterType="String" resultMap="BaseResultMap"> select * from sys_admin where psncode=#{psncode} </select> <select id="findByEmail" parameterType="String" resultMap="BaseResultMap"> select * from sys_admin where email=#{email} </select> </mapper>
8.配置spring 在resources文件中 添加spring-web.xml ，spring-service.xml ，spring-dao.xml
8.1 spring-web.xml
