这样就可以创建一个maven项目,可以看最下图的目录结构,但是这样的目录结构是不对的,需要做一些修改。
<dependency>
<groupId>javaxgroupId>
<artifactId>javaee-apiartifactId>
<version>7.0version>
dependency>
至此,完整的目录结构以及正确的项目完成。
下面主要介绍三大框架的整合,至于环境的搭建以及项目的创建,参看上面的博文。这次整合我分了2个配置文件,分别是spring-mybatis.xml,包含spring和mybatis的配置文件,还有个是spring-mvc的配置文件,此外有2个资源文件:jdbc.propertis和log4j.properties。
2.1Maven引入需要的JAR包
此处说明,这里我多引入了后面才能用到的的包,比如 mybatis的自动生成等,每个包都有注释名称,看下。

2.2、整合SpringMVC
2.2.1、配置spring-mvc.xml
配置里面的注释也很详细,主要是自动扫描控制器,视图模式,注解的启动这三个。
<beans xmlns="http://www.springframework.org/schema/beans"

2.2.2、配置web.xml文件
配置的spring-mvc的Servlet就是为了完成SpringMVC+MAVEN的整合。
web.xml
<web-app xmlns:xsi="http://www.w3.org/2001/XMLSchema-instance"
xmlns="http://java.sun.com/xml/ns/javaee"
xsi:schemaLocation="http://java.sun.com/xml/ns/javaee http://java.sun.com/xml/ns/javaee/web-app_3_0.xsd"

2.2.3、Log4j的配置
为了方便调试,一般都会使用日志来输出信息,Log4j是Apache的一个开放源代码项目,通过使用Log4j,我们可以控制日志信息输送的目的地是控制台、文件、GUI组件,甚至是套接口服务器、NT的事件记录器、UNIX Syslog守护进程等;我们也可以控制每一条日志的输出格式;通过定义每一条日志信息的级别,我们能够更加细致地控制日志的生成过程。
Log4j的配置很简单,而且也是通用的,下面给出一个基本的配置,换到其他项目中也无需做多大的调整,如果想做调整或者想了解Log4j的各种配置,参看我转载的一篇博文,很详细:http://blog.csdn.net/zhshulin/article/details/37937365
log4j.properties
log4j.rootLogger=INFO,Console,File
#定义日志输出目的地为控制台
log4j.appender.Console=org.apache.log4j.ConsoleAppender
log4j.appender.Console.Target=System.out
#可以灵活地指定日志输出格式,下面一行是指定具体的格式
log4j.appender.Console.layout = org.apache.log4j.PatternLayout
log4j.appender.Console.layout.ConversionPattern=[%c] - %m%n
#文件大小到达指定尺寸的时候产生一个新的文件
log4j.appender.File = org.apache.log4j.RollingFileAppender
#指定输出目录
log4j.appender.File.File = logs/ssm.log
#定义文件最大大小
log4j.appender.File.MaxFileSize = 10MB
# 输出所以日志,如果换成DEBUG表示输出DEBUG以上级别日志
log4j.appender.File.Threshold = ALL
log4j.appender.File.layout = org.apache.log4j.PatternLayout
log4j.appender.File.layout.ConversionPattern =[%p] [%d{yyyy-MM-dd HH\:mm\:ss}][%c]%m%n
###显示SQL语句部分
log4j.logger.com.ibatis=DEBUG
log4j.logger.com.ibatis.common.jdbc.SimpleDataSource=DEBUG
log4j.logger.com.ibatis.common.jdbc.ScriptRunner=DEBUG
log4j.logger.com.ibatis.sqlmap.engine.impl.SqlMapClientDelegate=DEBUG
log4j.logger.Java.sql.Connection=DEBUG
log4j.logger.java.sql.Statement=DEBUG
log4j.logger.java.sql.PreparedStatement=DEBUG
2.2.4、使用Jetty测试
UserController
package com.ssm.controller;
import javax.servlet.http.HttpServletRequest;
import org.slf4j.Logger;
import org.slf4j.LoggerFactory;
import org.springframework.stereotype.Controller;
import org.springframework.ui.Model;
import org.springframework.web.bind.annotation.RequestMapping;
import org.springframework.web.bind.annotation.RequestMethod;
import com.ssm.entity.User;
@Controller
public class UserController {
// /user/test?id=1
@RequestMapping(value="/user/test",method=RequestMethod.GET)
public String test(HttpServletRequest request,Model model){
int userId = Integer.parseInt(request.getParameter("id"));
System.out.println("userId:"+userId);
User user=null;
if (userId==1) {
user = new User();
user.setAge(11);
user.setId(1);
user.setPassword("123");
user.setName("javen");
}
System.out.println(user);
model.addAttribute("user", user);
return "welcome";
}
}
user.java
package com.ssm.entity;
public class User {
private Integer id;
private String name;
private String password;
private Integer age;
public Integer getId() {
return id;
}
public void setId(Integer id) {
this.id = id;
}
public String getName() {
return name;
}
public void setName(String name) {
this.name = name;
}
public String getPassword() {
return password;
}
public void setPassword(String password) {
this.password = password == null ? null : password.trim();
}
public Integer getAge() {
return age;
}
public void setAge(Integer age) {
this.age = age;
}
@Override
public String toString() {
return "User [id=" + id + ", name=" + name + ", password=" + password + ", age=" + age + "]";
}
}
welcome.jsp
<html>
<head>
<title>ssmtitle>
head>
<body>
<h2>Hello World!h2>
body>
html>
在浏览器中输入:http://localhost/user/test?id=1
到此 SpringMVC+Maven 整合完毕
2.3 Spring与MyBatis的整合
取消2.2.2 web.xml中注释的代码
2.3.1、建立JDBC属性文件
jdbc.properties(文件编码修改为utf-8,可在eclipse中右击文件选择编码格式)
driver=com.mysql.jdbc.Driver
url=jdbc:mysql://127.0.0.1:3306/test?useSSL=false
username=root
password=
#定义初始连接数
initialSize=0
#定义最大连接数
maxActive=20
#定义最大空闲
maxIdle=20
#定义最小空闲
minIdle=1
#定义最长等待时间
maxWait=60000
当前项目结构
2.3.2、建立spring-mybatis.xml配置文件
这个文件就是用来完成spring和mybatis的整合的。这里面也没多少行配置,主要的就是自动扫描,自动注入,配置数据库。注释也很详细,大家看看就明白了。
spring-mybatis.xml
<beans xmlns="http://www.springframework.org/schema/beans"
xmlns:xsi="http://www.w3.org/2001/XMLSchema-instance" xmlns:p="http://www.springframework.org/schema/p"
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-3.1.xsd
http://www.springframework.org/schema/context
http://www.springframework.org/schema/context/spring-context-3.1.xsd
http://www.springframework.org/schema/mvc
http://www.springframework.org/schema/mvc/spring-mvc-4.0.xsd">
<context:component-scan base-package="com.ssm" />
<bean id="propertyConfigurer"
class="org.springframework.beans.factory.config.PropertyPlaceholderConfigurer">
<property name="location" value="classpath:jdbc.properties" />
bean>
<bean id="dataSource" class="org.apache.commons.dbcp.BasicDataSource"
destroy-method="close">
<property name="driverClassName" value="${driver}" />
<property name="url" value="${url}" />
<property name="username" value="${username}" />
<property name="password" value="${password}" />
<property name="initialSize" value="${initialSize}">property>
<property name="maxActive" value="${maxActive}">property>
<property name="maxIdle" value="${maxIdle}">property>
<property name="minIdle" value="${minIdle}">property>
<property name="maxWait" value="${maxWait}">property>
bean>
<bean id="sqlSessionFactory" class="org.mybatis.spring.SqlSessionFactoryBean">
<property name="dataSource" ref="dataSource" />
<property name="mapperLocations" value="classpath:sqlmap/*.xml">property>
bean>
<bean class="org.mybatis.spring.mapper.MapperScannerConfigurer">
<property name="basePackage" value="com.ssm.dao" />
<property name="sqlSessionFactoryBeanName" value="sqlSessionFactory">property>
bean>
<bean id="transactionManager"
class="org.springframework.jdbc.datasource.DataSourceTransactionManager">
<property name="dataSource" ref="dataSource" />
bean>
beans>
经过以上步骤,我们已经完成了Spring和mybatis的整合,这样我们就可以编写一段测试代码来试试是否成功了。
2.4.1、创建测试用表
在数据库中建立一个测试表,这个表建的很简单,SQL语句为:
-- ----------------------------
-- Table structure for `user_d`
-- ----------------------------
DROP TABLE IF EXISTS `user_d`;
CREATE TABLE `user_d` (
`id` int(11) NOT NULL AUTO_INCREMENT,
`name` varchar(40) NOT NULL,
`password` varchar(255) NOT NULL,
`age` int(4) NOT NULL,
PRIMARY KEY (`id`)
) ENGINE=InnoDB AUTO_INCREMENT=3 DEFAULT CHARSET=utf8;
-- ----------------------------
-- Records of user_d
-- ----------------------------
INSERT INTO `user_d` VALUES ('1', '黄渤', '345', '24');
INSERT INTO `user_d` VALUES ('2', '徐峥', '123', '10');
UserMapper.java
package com.ssm.dao;
import com.ssm.entity.User;
public interface UserMapper {
User getUserById(int i);
}
UserMapper.xml
<mapper namespace="com.ssm.dao.UserMapper">
<resultMap id="user" type="com.ssm.entity.User">
<id column="id" jdbcType="INTEGER" property="id"/>
<result column="name" jdbcType="VARCHAR" property="name" />
<result column="password" jdbcType="VARCHAR" property="password" />
<result column="age" jdbcType="VARCHAR" property="age" />
resultMap>
<select id="getUserById" resultMap="user">
SELECT * FROM user_d where id=#{id}
select>
mapper>
修改controller方法
package com.ssm.controller;
import javax.servlet.http.HttpServletRequest;
import org.slf4j.Logger;
import org.slf4j.LoggerFactory;
import org.springframework.beans.factory.annotation.Autowired;
import org.springframework.stereotype.Controller;
import org.springframework.ui.Model;
import org.springframework.web.bind.annotation.RequestMapping;
import org.springframework.web.bind.annotation.RequestMethod;
import com.ssm.dao.UserMapper;
import com.ssm.entity.User;
@Controller
public class UserController {
@Autowired
private UserMapper userMapper;
// /user/test?id=1
@RequestMapping(value = "/user/test", method = RequestMethod.GET)
public String test(HttpServletRequest request, Model model) {
int userId = Integer.parseInt(request.getParameter("id"));
System.out.println("userId:" + userId);
User user = null;
if (userId == 1) {
user = new User();
user.setAge(11);
user.setId(1);
user.setPassword("123");
user.setName("javen");
} else if (userId == 2) {
// 根据id查询用户信息
user = userMapper.getUserById(userId);
}
System.out.println(user);
model.addAttribute("user", user);
return "welcome";
}
}
修改welcome.jsp
<html>
<head>
<title>ssmtitle>
head>
<body>
<h2>Hello World!h2>
hello ${user.name}
body>
html>
在浏览器中输入http://localhost/user/test?id=2 测试
至此ssm整合完毕!
下面介绍mybatis的自动生成
mybatis的自动生成有多种方法(比如:编写java代码运行、命令提示符运行、eclipse插件运行、maven Plugin运行),几种方法各有优缺点。
这里主要介绍使用 maven Plugin方式运行。
完成后项目结构
1,解开pom.xml中的注释
2.新建generatorConfig.xml文件
generatorConfig.xml
<generatorConfiguration>
<context id="MySqlContext" targetRuntime="MyBatis3" defaultModelType="flat">
<property name="beginningDelimiter" value="`"/>
<property name="endingDelimiter" value="`"/>
<commentGenerator>
<property name="suppressDate" value="true"/>
<property name="addRemarkComments" value="true"/>
commentGenerator>
<jdbcConnection driverClass="com.mysql.jdbc.Driver"
connectionURL="jdbc:mysql://localhost:3306/test"
userId="root"
password="111">
jdbcConnection>
<javaModelGenerator targetPackage="com.ssm.entity" targetProject="src\main\java">
<property name="trimStrings" value="true" />
javaModelGenerator>
<sqlMapGenerator targetPackage="sqlmap" targetProject="src\main\resources"/>
<javaClientGenerator type="XMLMAPPER" targetPackage="com.ssm.dao" targetProject="src\main\java"/>
<table tableName="user_d" domainObjectName="UserD">
<generatedKey column="id" sqlStatement="MySql"/>
table>
context>
generatorConfiguration>
3.运行
输入: clean mybatis-generator:generate
自动生成即可完成。
