使用idea2017搭建SSM框架(图文步骤)
搭建个ssm框架居然花费了我好长时间!特此记录!
需要准备的环境:
- idea 2017.1
- jdk1.8
- maven 3.3.9
请提前将idea与maven、jdk配置好,本次项目用的都是比较新的
注:配置完ide红线报错没关系!可以run!
步骤:
一、首先使用idea新建一个maven webapp项目
点击finish,第一次搭建可能会很慢,甚至可能需要vpn才能搭建成功
二、搭建目录结构
我这里列出的是搭建完了之后所有的目录和文件,诸位先把目录文件建起来,然后我在给出文件内容
这里的目录建好之后还需要设置一下,让idea识别目录作用,选择file-project structure
设置完成后ok
三、配置文件内容
pom.xml
<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.chatrobot</groupid> <artifactid>chatrobot</artifactid> <packaging>war</packaging> <version>1.0-snapshot</version> <name>chatrobot maven webapp</name> <url>http://maven.apache.org</url> <properties> <!-- 设置项目编码编码 --> <project.build.sourceencoding>utf-8</project.build.sourceencoding> <project.reporting.outputencoding>utf-8</project.reporting.outputencoding> <!-- spring版本号 --> <spring.version>4.3.5.release</spring.version> <!-- mybatis版本号 --> <mybatis.version>3.4.1</mybatis.version> </properties> <dependencies> <!-- java ee --> <dependency> <groupid>javax</groupid> <artifactid>javaee-api</artifactid> <version>7.0</version> </dependency> <!-- 单元测试 --> <dependency> <groupid>junit</groupid> <artifactid>junit</artifactid> <version>4.12</version> </dependency> <!-- 实现slf4j接口并整合 --> <dependency> <groupid>ch.qos.logback</groupid> <artifactid>logback-classic</artifactid> <version>1.2.2</version> </dependency> <!-- json --> <dependency> <groupid>com.fasterxml.jackson.core</groupid> <artifactid>jackson-databind</artifactid> <version>2.8.7</version> </dependency> <!-- 数据库 --> <dependency> <groupid>mysql</groupid> <artifactid>mysql-connector-java</artifactid> <version>5.1.41</version> <scope>runtime</scope> </dependency> <!-- 数据库连接池 --> <dependency> <groupid>com.mchange</groupid> <artifactid>c3p0</artifactid> <version>0.9.5.2</version> </dependency> <!-- mybatis --> <dependency> <groupid>org.mybatis</groupid> <artifactid>mybatis</artifactid> <version>${mybatis.version}</version> </dependency> <!-- mybatis/spring整合包 --> <dependency> <groupid>org.mybatis</groupid> <artifactid>mybatis-spring</artifactid> <version>1.3.1</version> </dependency> <!-- spring --> <dependency> <groupid>org.springframework</groupid> <artifactid>spring-core</artifactid> <version>${spring.version}</version> </dependency> <dependency> <groupid>org.springframework</groupid> <artifactid>spring-beans</artifactid> <version>${spring.version}</version> </dependency> <dependency> <groupid>org.springframework</groupid> <artifactid>spring-context</artifactid> <version>${spring.version}</version> </dependency> <dependency> <groupid>org.springframework</groupid> <artifactid>spring-jdbc</artifactid> <version>${spring.version}</version> </dependency> <dependency> <groupid>org.springframework</groupid> <artifactid>spring-tx</artifactid> <version>${spring.version}</version> </dependency> <dependency> <groupid>org.springframework</groupid> <artifactid>spring-web</artifactid> <version>${spring.version}</version> </dependency> <dependency> <groupid>org.springframework</groupid> <artifactid>spring-webmvc</artifactid> <version>${spring.version}</version> </dependency> <dependency> <groupid>org.springframework</groupid> <artifactid>spring-test</artifactid> <version>${spring.version}</version> </dependency> </dependencies> <build> <finalname>chatrobot</finalname> <plugins> <plugin> <groupid>org.apache.maven.plugins</groupid> <artifactid>maven-compiler-plugin</artifactid> <configuration> <!-- 设置jdk版本 --> <source>1.8</source> <target>1.8</target> </configuration> </plugin> </plugins> </build> </project>
注意右下角更新pom
logback.xml
<?xml version="1.0" encoding="utf-8"?> <configuration debug="true"> <appender name="stdout" class="ch.qos.logback.core.consoleappender"> <encoder> <pattern>%d{hh:mm:ss.sss} [%thread] %-5level %logger{36} - %msg%n</pattern> </encoder> </appender> <root level="debug"> <appender-ref ref="stdout"/> </root> </configuration>
这里可以控制输出格式和内容,有兴趣的可以自己设置

到这里基本上环境就搭建完成了,下面开始测试
四、测试
先导入一份数据库测试文件
create table `user` ( `id` int(11) not null auto_increment comment '用户id', `email` varchar(255) not null comment '用户邮箱', `password` varchar(255) not null comment '用户密码', `username` varchar(255) not null comment '用户昵称', `role` varchar(255) not null comment '用户身份', `status` int(1) not null comment '用户状态', `regtime` datetime not null comment '注册时间', `regip` varchar(255) not null comment '注册ip', primary key (`id`), unique key `email` (`email`) using btree ) engine=innodb auto_increment=2 default charset=utf8; insert into `user` values ('1', 'xxx', 'xxxxx', 'xxxxx', 'root', '0', '2017-03-28 09:40:31', '127.0.0.1'); set foreign_key_checks=1;
接下来配置类
usercontroller
package com.chatrobot.controller; import javax.servlet.http.httpservletrequest; import com.chatrobot.model.user; import com.chatrobot.service.iuserservice; import com.fasterxml.jackson.databind.objectmapper; import org.springframework.stereotype.controller; import org.springframework.web.bind.annotation.requestmapping; import javax.annotation.resource; import javax.servlet.http.httpservletresponse; import java.io.ioexception; @controller @requestmapping("/user") public class usercontroller { @resource private iuserservice userservice; @requestmapping("/showuser.do") public void selectuser(httpservletrequest request, httpservletresponse response) throws ioexception { request.setcharacterencoding("utf-8"); response.setcharacterencoding("utf-8"); long userid = long.parselong(request.getparameter("id")); user user = this.userservice.selectuser(userid); objectmapper mapper = new objectmapper(); response.getwriter().write(mapper.writevalueasstring(user)); response.getwriter().close(); } }
iuserdao
package com.chatrobot.dao; import com.chatrobot.model.user; public interface iuserdao { user selectuser(long id); }
user
package com.chatrobot.model; import java.util.date; public class user { private long id; private string email; private string password; private string username; private string role; private int status; private date regtime; private string regip; public long getid() { return id; } public void setid(int id) { this.id = id; } public string getemail() { return email; } public void setemail(string email) { this.email = email; } public string getpassword() { return password; } public void setpassword(string password) { this.password = password; } public string getusername() { return username; } public void setusername(string username) { this.username = username; } public string getrole() { return role; } public void setrole(string role) { this.role = role; } public int getstatus() { return status; } public void setstatus(int status) { this.status = status; } public date getregtime() { return regtime; } public void setregtime(date regtime) { this.regtime = regtime; } public string getregip() { return regip; } public void setregip(string regip) { this.regip = regip; } }
iuserservice
package com.chatrobot.service; import com.chatrobot.model.user; public interface iuserservice { public user selectuser(long userid); }
userserviceimpl
package com.chatrobot.service.impl; import com.chatrobot.dao.iuserdao; import com.chatrobot.model.user; import com.chatrobot.service.iuserservice; import org.springframework.stereotype.service; import javax.annotation.resource; @service("userservice") public class userserviceimpl implements iuserservice { @resource private iuserdao userdao; public user selectuser(long userid) { return this.userdao.selectuser(userid); } }
userdao.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"> <!-- 设置为iuserdao接口方法提供sql语句配置 --> <mapper namespace="com.chatrobot.dao.iuserdao"> <select id="selectuser" resulttype="user" parametertype="long"> select * from user where id = #{id} </select> </mapper>
然后新建个测试类,来测试mybatis
iuserdaotest
package com.chatrobot.dao; import com.chatrobot.model.user; import org.junit.test; import org.junit.runner.runwith; import org.springframework.beans.factory.annotation.autowired; import org.springframework.test.context.contextconfiguration; import org.springframework.test.context.junit4.springjunit4classrunner; // 加载spring配置文件 @runwith(springjunit4classrunner.class) @contextconfiguration({"classpath:spring-mybatis.xml"}) public class iuserdaotest { @autowired private iuserdao dao; @test public void testselectuser() throws exception { long id = 1; user user = dao.selectuser(id); system.out.println(user.getusername()); } }
运行后结果应该是会在控制台输出id为1的用户名,没成功的话就找bug去吧...
继续新建个页面来测试springmvc和mybatis
index.html
<!doctype html> <html> <head> <meta charset="utf-8"> <title>test</title> </head> <script> function selectuser() { var xmlhttp = new xmlhttprequest(); xmlhttp.onreadystatechange = function () { if (xmlhttp.readystate == 4 && xmlhttp.status == 200) { document.getelementbyid("test").innerhtml = xmlhttp.responsetext; } } xmlhttp.open("post", "user/showuser.do", true); xmlhttp.setrequestheader("content-type", "application/x-www-form-urlencoded"); xmlhttp.send("id=1"); } </script> <body> <p id="test">hello world!</p> <button type="button" onclick="selectuser()">onclick test</button> </body> </html>
新建完成后配置项目运行环境,点击run-edit configurations...
点击加号新建运行环境,选择tomcat server-local
选中新建好的服务器,右边选择deployment,点击加号-atifact...
选择第二项
然后在右边application context配置你的项目名
最后运行项目,在打开的页面中点击按钮测试,成功的话会在页面上显示id为1的用户信息
