spring-boot（一）环境搭建

spring boot 学习记录

项目的目录结构

解释：

1. 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/xsd/maven-4.0.0.xsd">  <modelVersion>4.0.0</modelVersion>  <groupId>cn.springbooot</groupId>  <artifactId>SpringBootFrist</artifactId>  <version>0.0.1-SNAPSHOT</version>  <packaging>jar</packaging>  <name>SpringBootFrist</name>  <url>http://maven.apache.org</url>  <properties>    <project.build.sourceEncoding>UTF-8</project.build.sourceEncoding>  </properties>    <parent>        <groupId>org.springframework.boot</groupId>        <artifactId>spring-boot-starter-parent</artifactId>        <version>1.2.7.RELEASE</version>    </parent>    <dependencies>        <dependency>            <groupId>org.springframework.boot</groupId>            <artifactId>spring-boot-starter-web</artifactId>        </dependency>        <dependency>           <groupId>org.springframework.boot</groupId>           <artifactId>spring-boot-starter-data-jpa</artifactId>        </dependency>        <!--  日志文件打印 -->        <dependency>            <groupId>org.springframework.boot</groupId>            <artifactId>spring-boot-starter-logging</artifactId>        </dependency>        <!-- MYSQL -->        <dependency>            <groupId>mysql</groupId>            <artifactId>mysql-connector-java</artifactId>         </dependency>         <dependency>            <groupId>org.springframework.boot</groupId>            <artifactId>spring-boot-starter-web</artifactId>        </dependency>        <dependency>        　　<groupId>org.mybatis.spring.boot</groupId>        　　<artifactId>mybatis-spring-boot-starter</artifactId>        　　<version>1.1.1</version>        </dependency>        <!--  使用thymeleaf  模版引擎   -->        <dependency>            <groupId>org.springframework.boot</groupId>            <artifactId>spring-boot-starter-thymeleaf</artifactId>            <version>1.4.3.RELEASE</version>        </dependency>        <!--  POI 配置信息 -->        <dependency>             <groupId>org.apache.poi</groupId>             <artifactId>poi</artifactId>             <version>3.11</version>         </dependency>      </dependencies></project>

2.application.properties

1.数据库用的是mysql
2.server.port 修改启动端口号
3.数据库操作用的JPA，hibernate配合
4.前端框架用的是：thymeleaf ，
5.样式插件： bootStrap

# mysql 配置 spring.datasource.url=jdbc:mysql://127.0.0.1:3306/testspring.datasource.username=rootspring.datasource.password=rootspring.datasource.driver-class-name=com.mysql.jdbc.Driverspring.datasource.max-idle=10spring.datasource.max-wait=10000spring.datasource.min-idle=5spring.datasource.initial-size=5# 服务器端口、连接时间server.port=8011server.session.timeout=10server.tomcat.uri-encoding=UTF-8#JPA Configuration:  spring.jpa.database=MySQLspring.jpa.show-sql=true  spring.jpa.generate-ddl=true  spring.jpa.hibernate.ddl-auto=update spring.jpa.hibernate.naming.physical-strategy=org.hibernate.boot.model.naming.PhysicalNamingStrategyStandardImpl#spring.jpa.database-platform=org.hibernate.dialect.MySQL5Dialect  #spring.jpa.hibernate.naming_strategy=org.hibernate.cfg.ImprovedNamingStrategy  #thymeleaf startspring.thymeleaf.mode=HTML5spring.thymeleaf.encoding=UTF-8spring.thymeleaf.content-type=text/html#开发时关闭缓存,不然没法看到实时页面spring.thymeleaf.cache=false#thymeleaf enddebug=truespring.jpa.show-sql=true

2.ReadingListApplication.java 是启动类

其中需要注意：@ComponentScan(basePackages={“cn.springbooot.SpringBootFrist”})
扫描的路径

package cn.springbooot.SpringBootFrist;import org.springframework.boot.SpringApplication;import org.springframework.boot.autoconfigure.SpringBootApplication;import org.springframework.context.annotation.ComponentScan;@SpringBootApplication@ComponentScan(basePackages={"cn.springbooot.SpringBootFrist"})public class ReadingListApplication {    public static void main(String[] args){        SpringApplication.run(ReadingListApplication.class, args);    }}

4. 对于前端thymeleaf引入

首先需要在路径：/src/main/resources新建两个包：
命名分别为： static–(存放静态的资源)，例如bootStarp
templates–(存放页面的资源)

如果不新建会报错，因为thtmeleaf默认的包就是这两个。

ThymeleafProperties.javapublic static final String DEFAULT_PREFIX = "classpath:/templates/";    public static final String DEFAULT_SUFFIX = ".html";    public ThymeleafProperties() {        this.checkTemplateLocation = true;        this.prefix = "classpath:/templates/"; // 默认存放的路径        this.suffix = ".html";  // 默认后缀是html        this.mode = "HTML5";    // 模式html5        this.encoding = "UTF-8"; // 编码格式是 UTF-8        this.contentType = "text/html";        this.cache = true;      // 是否开启缓存        this.enabled = true;    }

5. bootstarp

下载直接放在新建static下就可以了

6. 进行测试

SampleController .java

package cn.springbooot.SpringBootFrist.Controller;import org.springframework.stereotype.Controller;import org.springframework.web.bind.annotation.RequestMapping;import org.springframework.web.bind.annotation.ResponseBody;@Controllerpublic class SampleController {    @RequestMapping("/")    String home(ModelMap map){        List<UserLogin> listus = new ArrayList<UserLogin>();        UserLogin ul = new UserLogin();        ul.setId(1);        ul.setUsername("小名");        ul.setPassword("1234");        UserLogin u1 = new UserLogin();        u1.setId(2);        u1.setUsername("小明");        u1.setPassword("1234");        UserLogin u2 = new UserLogin();        u2.setId(2);        u2.setUsername("笑话");        u2.setPassword("1234");        UserLogin u3 = new UserLogin();        u3.setId(3);        u3.setUsername("小刚");        u3.setPassword("1234");        listus.add(u1);        listus.add(u2);        listus.add(u3);        listus.add(ul);        map.addAttribute("ul", listus);        map.addAttribute("word", "世界很美好");        return "index";    }}

main.html
作为一个公共的样式和js引入

<head><meta content="text/html;charset=UTF-8"></meta><meta http-equiv="X-UA-Compatible" content="IE=edge"></meta><meta name="viewport" content="width=device-width,initial-scale=1"></meta><link th:href="@{bootstrap/css/bootstrap.min.css}" rel="stylesheet"/><link th:href="@{bootstrap/css/bootstrap-theme.min.css}" rel="stylesheet"/></head><body></body>

index.html
th:text 等都是thymeleaf的语法

<!DOCTYPE html><html><head th:include="main"></head><body>    <div class="panel panel-primary">        <div class="panel-heading">            <h3 class="panel-title">访问model</h3>        </div>        <div class="panel-body">            <span th:text="${word}"></span>        </div>    </div>    <div th:if="${not #lists.isEmpty(ul)}">        <div class="panel panel-primary">            <h3 class="panel-title">列表</h3>        </div>        <div class="panel-body">            <ul class="list-group">                <li class="list-group-item" th:each="user:${ul}">                    <span th:text="${user.id}"></span>                    <span th:text="${user.loginName}"></span>                    <span th:text="${user.loginPassword}"></span>                </li>            </ul>        </div>    </div></body></html>
