1.在myeclipse里创建一个maven项目。file>new>maven project：
勾选图中红色部分，然后点击next。
2.填写下图中红色部分然后点击finish。
3.此时一个maven项目已经生成，目录结构如下：
4.打开pom.xml在里面编辑如下内容：

spring.freemarker.settings.classic_compatible=true
spring.freemarker.order=1
#server
server.port=80

相应的配置需要根据自己的实际情况去做修改。
7.在在src/main/resources下创建mybatis目录并在目录下创建usermapper.xml文件：
?

<?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">
<mapper namespace="com.lm.dao.usermapper">
<select id="findall" resulttype="com.lm.model.user" parametertype="java.lang.string">
select id, username,password,email from t_user
</select>
</mapper>
|
8.创建usercontroller类和视图文件：

package com.lm.controller;
import java.util.list;
import org.springframework.beans.factory.annotation.autowired;
import org.springframework.stereotype.controller;
import org.springframework.ui.modelmap;
import org.springframework.web.bind.annotation.requestmapping;
import com.lm.model.user;
import com.lm.service.userservice;
@controller
@requestmapping("/user")
public class usercontroller {
@autowired
private userservice userservice;
@requestmapping("/list")
public string list(modelmap map){
list<user> userlist=userservice.findall();
map.addattribute("userlist", userlist);
return "/user/list";
}
}
|
可以看出list方法返回的是一个字符串，因为我们给应用加载了freemarker模块做视图展现，所以需要创建一个list模板，模板所在的目录在application.properties中指定为spring.freemarker.template-loader-path=classpath:/templates/，所以我们需要在src/main/resources下创建templates目录，然后在templates下创建user目录，模板文件后缀在application.properties中指定为spring.freemarker.suffix=.ftl，所以最终建立一个list.ftl文件:

<!doctype html>
<html lang="en">
<head>
<meta charset="utf-8">
<title>用户列表</title>
</head>
<body>
<table>
<tr>
<th>id</th><th>用户名</th><th>密码</th><th>邮箱</th>

<#list userlist as user>
<tr>
<td>${user.id}</td> <td>${user.username}</td><td>${user.password}</td><td>${user.email}</td>
</tr>
</#list>
</table>
</body>
</html>

模板文件所在位置的目录结构如下图:

public class userserviceimpl implements userservice{

package com.lm.model;
public class user {
private integer id;
private string username;
private string password;
private string email;
public integer getid() {
return id;
}
public void setid(integer id) {
this.id = id;
}
public string getusername() {
return username;
}
public string getemail() {
return email;
}
public void setemail(string email) {
this.email = email;
}
public void setusername(string username) {
this.username = username;
}
public string getpassword() {
return password;
}
public void setpassword(string password) {
this.password = password;
}
}

13.至此spring-boot框架已搭建完成，然后在application.java中run as >java application此时在控制台会看到如下日志输出：
14.打开浏览器在地址栏输入http://localhost/user/list便可以看到以下效果:
15.在pom.xml文件上右键run as>maven install可将项目打包为jar文件，生成的jar在target目录下，可以将此jar拷贝到服务器上通过"java -jar 最终生成jar包的名字"运行项目。
16.本项目的源码已经上传到，有需要的朋友可以自行下载
以上就是本文的全部内容，希望对大家的学习有所帮助，也希望大家多多支持快网idc。
