Eclipse+Maven 项目创建
★：jar包下载不了的话可能是镜像里没有这个版本，换个低版本的就行
★：eclipse工程validating很慢，可以先关掉验证（一般对项目没什么影响）
★：eclipse工程pom.xml文件报错 到仓库 删除所有以.lastupdate结尾的文件
★：maven下载jar包慢
解决办法就是到setting文件中，配上<mirror>标签的内容 -->
加在<mirrors>里面
<mirror>
<id>alimaven</id>
<name>aliyun maven</name>
<url>http://maven.aliyun.com/nexus/content/groups/public/</url>
<mirrorOf>central</mirrorOf>
</mirror>
0：maven .setting文件配置jdk版本
在你的maven/config/setting.xml文件的<properties>属性中加上这段代码
<profile>
<id>jdk-1.8</id>
<activation>
<activeByDefault>true</activeByDefault>
<jdk>1.8</jdk>
</activation>
<properties>
<maven.compiler.source>1.8</maven.compiler.source>
<maven.compiler.target>1.8</maven.compiler.target>
<maven.compiler.compilerVersion>1.8</maven.compiler.compilerVersion>
</properties>
1：项目创建
在 Package Explorer 空白处右键创建Maven Project
为你的web项目配置tomcat环境
在你的项目右键→Bulid Path→Add Libraries→server runtime→添加tomcat
完成后如图所示：
3.更改Deployment Assembly设置
将图中用不到的三个配置Remove掉
4.修改Project Fact
在pom.xml文件中的bulid节点加上
<plugins>
<plugin>
<groupId>org.apache.maven.plugins</groupId>
<artifactId>maven-compiler-plugin</artifactId>
<configuration>
<source>1.8</source>
<target>1.8</target>
</configuration>
</plugin>
</plugins>
然后对项目alt+F5 更新项目
创建web.xml文件
注意！ 第一次创建出来的web.xml文件还不是3.1 要删除然后再创建一次。 这估计是它的bug吧
6.在pom文件中添加依赖
①：配置<dependencies>标签
<properties>
<!-- Spring版本号 -->
<spring.version>4.3.8.RELEASE</spring.version>
<!-- log4j日志文件管理包版本 -->
<slf4j.version>1.6.6</slf4j.version>
<log4j.version>1.2.12</log4j.version>
<!-- junit版本号 -->
<junit.version>4.10</junit.version>

</properties>

7：创建ssm框架用到的配置文件
7.1：创建log4j文件。内容如下：
#USE THIS SETTING FOR OUTPUT MYBATIS`s SQL ON THE CONSOLElog4j.rootLogger=DEBUG, Console#Consolelog4j.appender.Console=org.apache.log4j.ConsoleAppenderlog4j.appender.Console.layout=org.apache.log4j.PatternLayoutlog4j.appender.Console.layout.ConversionPattern=%d [%t] %-5p [%c] - %m%nlog4j.logger.java.sql.ResultSet=INFOlog4j.logger.org.apache=INFOlog4j.logger.java.sql.Connection=DEBUGlog4j.logger.java.sql.Statement=DEBUGlog4j.logger.java.sql.PreparedStatement=DEBUG7.2：在mybatis文件夹下创建mybatis-config.xml 文件，内容如下：

7.6:在properties下创建jdbc.properties
jdbc.driverClassName=com.mysql.jdbc.Driver
jdbc.url=jdbc:mysql://localhost:3306/ssm
jdbc.user=root
创建java文件
8.1 目录结构

8.6 UserService
package com.ssm.service;
import com.ssm.model.User;
import org.springframework.stereotype.Service;
public interface UserService {
User selectUserById(Integer userId);

8.7 UserServiceImpl
package com.ssm.service;
import org.springframework.beans.factory.annotation.Autowired;
import org.springframework.stereotype.Service;
import com.ssm.dao.UserDao;
import com.ssm.model.User;
@Service
public class UserServiceImpl implements UserService{
@Autowired
private UserDao userDao;
public User selectUserById(Integer userId) {
return userDao.selectUserById(userId);
}
}
9：数据库搭建
CREATE TABLE `t_user` (
`USER_ID` int(11) NOT NULL AUTO_INCREMENT,
`USER_NAME` char(30) NOT NULL,
`USER_PASSWORD` char(10) NOT NULL,
`USER_EMAIL` char(30) NOT NULL,
PRIMARY KEY (`USER_ID`),
KEY `IDX_NAME` (`USER_NAME`)
) ENGINE=InnoDB AUTO_INCREMENT=11 DEFAULT CHARSET=utf8
INSERT INTO t_user (USER_ID, USER_NAME, USER_PASSWORD, USER_EMAIL) VALUES (1, '谢彦杰', '12345678', '18719394156@63.com');
INSERT INTO t_user (USER_ID, USER_NAME, USER_PASSWORD, USER_EMAIL) VALUES (2, 'eangie', '123', 'aaa@126.com');
INSERT INTO t_user (USER_ID, USER_NAME, USER_PASSWORD, USER_EMAIL) VALUES (3, 'eangie', '123', 'aaa@126.com');
INSERT INTO t_user (USER_ID, USER_NAME, USER_PASSWORD, USER_EMAIL) VALUES (4, 'eangie', '123', 'aaa@126.com');
10.在src/main/webapp /view下创建index.jsp
<%@ page language="java" contentType="text/html; charset=UTF-8"
pageEncoding="UTF-8"%>
<!DOCTYPE html PUBLIC "-//W3C//DTD HTML 4.01 Transitional//EN" "http://www.w3.org/TR/html4/loose.dtd">
