SSM整合模板

环境搭建

1. 新建一个Maven项目，SSM ，右键项目名添加web的支持。

2. 导入相关的pom依赖。

<dependencies>

    <!--Junit-->

    <dependency>

        <groupId>junit</groupId>

        <artifactId>junit</artifactId>

        <version>4.12</version>

    </dependency>

    <!-- 数据库连接池 -->

    <dependency>
          <groupId>com.alibaba</groupId>
          <artifactId>druid</artifactId>
          <version>1.1.10</version>
    </dependency>

    <!--Servlet - JSP -->

        <dependency>

3. Maven资源过滤设置

<build>

    <resources>

        <resource>

            <directory>src/main/java</directory>

            <includes>

                <include>**/*.properties</include>

                <include>**/*.xml</include>

            </includes>

            <filtering>false</filtering>

        </resource>

        <resource>

            <directory>src/main/resources</directory>

            <includes>

                <include>**/*.properties</include>

                <include>**/*.xml</include>

            </includes>

            <filtering>false</filtering>

        </resource>

    </resources>

</build>

4. 建立基本结构和配置框架

• com.hsz.pojo
• com.hsz.dao
• com.hsz.service
• com.hsz.controller

5. 配置文件

• database.properties

jdbc.driver=com.mysql.jdbc.Driver
jdbc.url=jdbc:mysql://localhost:3306/ssm?useSSL=false&useUnicode=true&characterEncoding=UTF-8
jdbc.username=root
jdbc.password=root

• log4j.properties

#将等级为DEBUG的日志信息输出到console和file这两个目的地，console和file的定义在下面的代码
log4j.rootLogger=DEBUG,console,file

#控制台输出的相关设置
log4j.appender.console = org.apache.log4j.ConsoleAppender
log4j.appender.console.Target = System.out
log4j.appender.console.Threshold=DEBUG
log4j.appender.console.layout = org.apache.log4j.PatternLayout
log4j.appender.console.layout.ConversionPattern=[%c]-%m%n

#文件输出的相关设置
log4j.appender.file = org.apache.log4j.RollingFileAppender
log4j.appender.file.File=./log/kuang.log
log4j.appender.file.MaxFileSize=10mb
log4j.appender.file.Threshold=DEBUG
log4j.appender.file.layout=org.apache.log4j.PatternLayout
log4j.appender.file.layout.ConversionPattern=[%p][%d{yy-MM-dd}][%c]%m%n

#日志输出级别
log4j.logger.org.mybatis=DEBUG
log4j.logger.java.sql=DEBUG
log4j.logger.java.sql.Statement=DEBUG
log4j.logger.java.sql.ResultSet=DEBUG
log4j.logger.java.sql.PreparedStatement=DEBUG

• Mapper.xml

<?xml version="1.0" encoding="UTF-8" ?>
