Spring+SpringMvc+Mybatis框架集成搭建教程二(依赖配置及框架整合)
依赖导入以及框架整合
(1).打开项目的pom.xml文件，声明依赖
<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/maven-v4_0_0.xsd"> <modelVersion>4.0.0</modelVersion> <groupId>com.hafiz.www</groupId> <artifactId>ssm</artifactId> <packaging>war</packaging> <version>1.0-SNAPSHOT</version> <name>ssm Maven Webapp</name> <url>http://maven.apache.org</url> <properties> <spring.version>4.2.6.RELEASE</spring.version> <mybatis.version>3.2.8</mybatis.version> <mybatis-spring.version>1.2.2</mybatis-spring.version> <servlet.version>3.0.1</servlet.version> <druid.version>1.0.13</druid.version> <jsp-api.version>2.1</jsp-api.version> <jstl.version>1.2</jstl.version> <mysql.connector.version>5.1.38</mysql.connector.version> <aspectj.version>1.8.6</aspectj.version> <commons.fileupload.version>1.3.1</commons.fileupload.version> <jackson.version>2.5.4</jackson.version> <log4j.version>1.2.17</log4j.version> <slf4j.version>1.7.7</slf4j.version> </properties> <dependencies> <dependency> <groupId>junit</groupId> <artifactId>junit</artifactId> <version>3.8.1</version> <scope>test</scope> </dependency> <dependency> <groupId>org.springframework</groupId> <artifactId>spring-core</artifactId> <version>${spring.version}</version> </dependency> <dependency> <groupId>org.springframework</groupId> <artifactId>spring-context</artifactId> <version>${spring.version}</version> <type>jar</type> </dependency> <dependency> <groupId>org.springframework</groupId> <artifactId>spring-webmvc</artifactId> <version>${spring.version}</version> </dependency> <dependency> <groupId>org.springframework</groupId> <artifactId>spring-jdbc</artifactId> <version>${spring.version}</version> </dependency> <dependency> <groupId>org.springframework</groupId> <artifactId>spring-aop</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-orm</artifactId> <version>${spring.version}</version> </dependency> <dependency> <groupId>org.mybatis</groupId> <artifactId>mybatis</artifactId> <version>${mybatis.version}</version> </dependency> <dependency> <groupId>org.mybatis</groupId> <artifactId>mybatis-spring</artifactId> <version>${mybatis-spring.version}</version> </dependency> <dependency> <groupId>org.springframework</groupId> <artifactId>spring-beans</artifactId> <version>${spring.version}</version> </dependency> <dependency> <groupId>org.aspectj</groupId> <artifactId>aspectjweaver</artifactId> <version>${aspectj.version}</version> </dependency> <dependency> <groupId>commons-fileupload</groupId> <artifactId>commons-fileupload</artifactId> <version>${commons.fileupload.version}</version> </dependency> <dependency> <groupId>com.fasterxml.jackson.core</groupId> <artifactId>jackson-core</artifactId> <version>${jackson.version}</version> </dependency> <dependency> <groupId>com.fasterxml.jackson.core</groupId> <artifactId>jackson-databind</artifactId> <version>${jackson.version}</version> </dependency> <dependency> <groupId>javax.servlet</groupId> <artifactId>javax.servlet-api</artifactId> <version>${servlet.version}</version> <scope>provided</scope> </dependency> <dependency> <groupId>javax.servlet.jsp</groupId> <artifactId>jsp-api</artifactId> <version>${jsp-api.version}</version> <scope>provided</scope> </dependency> <dependency> <groupId>javax.servlet</groupId> <artifactId>jstl</artifactId> <version>${jstl.version}</version> </dependency> <dependency> <groupId>com.alibaba</groupId> <artifactId>druid</artifactId> <version>${druid.version}</version> </dependency> <dependency> <groupId>mysql</groupId> <artifactId>mysql-connector-java</artifactId> <version>${mysql.connector.version}</version> </dependency> <dependency> <groupId>log4j</groupId> <artifactId>log4j</artifactId> <version>${log4j.version}</version> </dependency> <dependency> <groupId>org.slf4j</groupId> <artifactId>slf4j-api</artifactId> <version>${slf4j.version}</version> </dependency> <dependency> <groupId>org.slf4j</groupId> <artifactId>slf4j-log4j12</artifactId> <version>${slf4j.version}</version> </dependency> </dependencies> <build> <finalName>ssm</finalName> </build> </project>
(2).在项目的resources文件夹下新建jdbc.properties文件
jdbc.driver=com.mysql.jdbc.Driver
jdbc.url=jdbc:mysql://192.168.20.196:3306/dev?useUnicode=true&characterEncoding=UTF-8
jdbc.username=root
jdbc.password=123456
jdbc.maxActive=30
jdbc.minIdle=5
(3).在项目的resources文件夹下新建log4j.properties文件
### set log levels ###
log4j.rootLogger = ERROR , stdout , D , E , F
### 输出到控制台 ###
log4j.appender.stdout = org.apache.log4j.ConsoleAppender
log4j.appender.stdout.Target = System.out
log4j.appender.stdout.layout = org.apache.log4j.PatternLayout
log4j.appender.stdout.layout.ConversionPattern = %-d{yyyy-MM-dd HH:mm:ss} [ %p ] [ %l-%t:%r ] - [ %X{ip} %X{userName}] %m%n
## 输出到日志文件 ###
log4j.appender.D = org.apache.log4j.DailyRollingFileAppender
log4j.appender.D.DatePattern = '.'yyyyMMdd
log4j.appender.D.File = logs/wap/warn.log
log4j.appender.D.Append = true
log4j.appender.D.Threshold = WARN
log4j.appender.D.layout = org.apache.log4j.PatternLayout
log4j.appender.D.encoding=UTF-8
log4j.appender.D.layout.ConversionPattern = %-d{yyyy-MM-dd HH:mm:ss} [ %p ] [ %l-%t:%r ] - [ %X{ip} %X{userName}] %m%n
## 保存异常信息到单独文件 ###
log4j.appender.E = org.apache.log4j.DailyRollingFileAppender
log4j.appender.E.File = logs/wap/error.log
log4j.appender.E.DatePattern = '.'yyyyMMdd
log4j.appender.E.Append = true
log4j.appender.E.Threshold = ERROR
log4j.appender.E.layout = org.apache.log4j.PatternLayout
log4j.appender.E.encoding=UTF-8
log4j.appender.E.layout.ConversionPattern = %-d{yyyy-MM-dd HH:mm:ss} [ %p ] [ %l-%t:%r ] - [ %X{ip} %X{userName}] %m%n
## 保存异常信息到单独文件 ###
log4j.appender.F = org.apache.log4j.DailyRollingFileAppender
log4j.appender.F.File = logs/wap/debug.log
log4j.appender.F.DatePattern = '.'yyyyMMdd
log4j.appender.F.Append = true
log4j.appender.F.Threshold = DEBUG
log4j.appender.F.layout = org.apache.log4j.PatternLayout
log4j.appender.F.encoding=UTF-8
log4j.appender.F.layout.ConversionPattern = %-d{yyyy-MM-dd HH:mm:ss} [ %p ] [ %l-%t:%r ] - [ %X{ip} %X{userName}] %m%n
(4).在项目的resources文件夹下新建mapper、spring、mybatis三个文件夹分别用来存放mybatis的mapper xml文件以及spring的配置文件以及mybatis的配置文件。
(5).在项目的resources文件夹下的mybatis文件夹下新建mybatis-config.xml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> <!-- 全局配置setting,根据需要进行配置 --> <!--<settings> <setting name="" value=""/> </settings>--> <!-- 设置别名 --> <typeAliases> <!-- 批量进行设置别名 --> <package name="com.hafiz.www.po"/> </typeAliases> <!-- 使用自动扫描器时，mapper.xml文件如果和mapper.java接口在一个目录则此处不用定义mappers --> <!-- <mappers> <package name="com.hafiz.www.mapper" /> </mappers> --> </configuration>
(6).在项目的resources文件夹下的spring文件夹下新建以下xml文件并进行整合配置

(7).在webapp下面创建js、css、img三个文件夹分别用来存放网站的脚本文件、样式文件以及图片文件
至此，Spring、SpringMvc、Mybatis的整合完毕！
