4、SpringBoot Web开发

1、创建SpringBoot应用，选中我们需要的模块；

2、SpringBoot已经默认将这些场景配置好了，只需要在配置文件中指定少量配置就可以运行起来；

3、自己编写业务代码。

 

自动配置原理？

      这个场景SpringBoot帮我们配置了什么？能不能修改？能修改哪些配置？能不能扩展？

 

 

 

 

创建新的工程：

 

 

 

 

 

 

 

 

 1、所有 /webjars/** ，都去 classpath:/META-INF/resources/webjars/ 找资源；
      webjars：以jar包的方式引入静态资源；

 

 

 

 

 

2、"/**" 访问当前项目的任何资源，都去（静态资源的文件夹）找映射

 

 

 localhost:8080/abc === 去静态资源文件夹里面找abc


3、欢迎页； 静态资源文件夹下的所有index.html页面；被"/**"映射；
localhost:8080/ 找index页面


4、所有的 **/favicon.ico 都是在静态资源文件下找；

 

 

在public文件夹下创建index.html文件

 

 

<!DOCTYPE html>
<html lang="en">
<head>
    <meta charset="UTF-8">
    <title>Title</title>
</head>
<body>
    <h1>首页</h1>
</body>
</html>

 

 

运行主程序：

 

 

 

访问地址 http://localhost:8081/

 

 

 

 

 

 

 

 

 

 

模板引擎

JSP、Velocity、Freemarker、Thymeleaf

 

 

SpringBoot推荐的Thymeleaf；
语法更简单，功能更强大；
 引入依赖

      <dependency>
            <groupId>org.springframework.boot</groupId>
            <artifactId>spring-boot-starter-thymeleaf</artifactId>
        </dependency>

 

 

引入版本信息

 

 

 

        <thymeleaf.version>3.0.9.RELEASE</thymeleaf.version>
		<!-- 布局功能的支持程序  thymeleaf3主程序  layout2以上版本 -->
		<!-- thymeleaf2   layout1-->
	<thymeleaf-layout-dialect.version>2.2.2</thymeleaf-layout-dialect.version>

　　

Thymeleaf使用

 

 

 只要我们把HTML页面放在classpath:/templates/，thymeleaf就能自动渲染

 

 

编写一个HelloController类

package com.atguigu.springboot.controller;

import org.springframework.stereotype.Controller;
import org.springframework.web.bind.annotation.RequestMapping;
import org.springframework.web.bind.annotation.ResponseBody;

@Controller
public class HelloController {
     @ResponseBody
    @RequestMapping("/hello")
    public String hello(){
         return "Hello World!";
     }

     @RequestMapping("/success")
      public String success(){
         //classpath:/templates/success.html
         return "success";
     }
}

 

 

编写success.html文件

 

 

 

<!DOCTYPE html>
<html lang="en" xmlns:th="http://www.thymeleaf.org">
<head>
    <meta charset="UTF-8">
    <title>Title</title>
</head>
<body>
<h1>成功！</h1>

</body>
</html>

 

 

 

运行主程序：

 

 

 

访问地址  http://localhost:8081/success

 

 

使用：

     1、导入thymeleaf的名称空间

<html lang="en" xmlns:th="http://www.thymeleaf.org">

 

 

 

2、使用thymeleaf的语法

 

 

<!DOCTYPE html>
<html lang="en" xmlns:th="http://www.thymeleaf.org">
<head>
    <meta charset="UTF-8">
    <title>Title</title>
</head>
<body>
   <h1>成功！</h1>
   <!--th:text 将div里面的文本内容设置为 -->
   <div th:text="${hello}"> </div>
</body>
</html>

 

 

 

访问地址 http://localhost:8081/success

 

 

   3、语法规则

     1）、th:text 改变当前元素里面的文本内容；

             th:任意html属性；来替换原生属性的值

 

     

 

 

 

<!DOCTYPE html>
<html lang="en" xmlns:th="http://www.thymeleaf.org">
<head>
    <meta charset="UTF-8">
    <title>Title</title>
</head>
<body>
<hr>
   <h1>成功！</h1>
   <!--th:text 将div里面的文本内容设置为 -->
   <div id="div01" class="myDiv" th:id="${hello}"  th:class="${hello}" th:text="${hello}"> </div>
  <hr/>
<div th:text="${hello}"> </div>
<div th:utext="${hello}"></div>
  <hr/>

<!-- th:each每次遍历都会生成当前这个标签： 3个h4 -->
<h4 th:text="${user}" th:each="user:${users}"> </h4>
<hr/>
<h4>
    <span th:each="user:${users}">[[${user}]] </span>
</h4>
</body>
</html>

 

 

 

 

 

package com.atguigu.springboot.controller;

import org.springframework.stereotype.Controller;
import org.springframework.web.bind.annotation.RequestMapping;
import org.springframework.web.bind.annotation.ResponseBody;

import java.util.Arrays;
import java.util.Map;

@Controller
public class HelloController {
    @ResponseBody
    @RequestMapping("/hello")
    public String hello(){
         return "Hello World!";
     }

     //查出一些数据，在页面展示
     @RequestMapping("/success")
      public String success(Map<String,Object> map){
         map.put("hello","<h1>你好</h1>");
         map.put("users", Arrays.asList("zhangsan","lisi","wangwu"));
         return "success";
     }
}

 

 

运行主程序：

 

 

 

 

 

访问地址   http://localhost:8081/success

 

 

三、SpringMVC自动配置
https://docs.spring.io/spring-boot/docs/1.5.10.RELEASE/reference/htmlsingle/#boot-features-developingweb-applications

 

 

 

 

 

 

 

 

原理：
1）、WebMvcAutoConfiguration是SpringMVC的自动配置类
2）、在做其他自动配置时会导入；@Import(EnableWebMvcConfiguration.class)
3）、容器中所有的WebMvcConfigurer都会一起起作用；
4）、我们的配置类也会被调用；
效果：SpringMVC的自动配置和我们的扩展配置都会起作用；
 

 

 

新建 MyMvcConfig类

 

 

package com.atguigu.springboot.config;

import org.springframework.context.annotation.Configuration;
import org.springframework.web.servlet.config.annotation.ViewControllerRegistry;
import org.springframework.web.servlet.config.annotation.WebMvcConfigurerAdapter;

@Configuration
public class MyMvcConfig extends WebMvcConfigurerAdapter {
    @Override
    public void addViewControllers(ViewControllerRegistry registry){
        //浏览器发送 /atguigu 请求来到 success
        registry.addViewController("/atguigu").setViewName("success");
    }
}

 

 

 

浏览器访问地址  http://localhost:8081/atguigu

 

 

 

 

 

 

 

 

 


原理：
为什么@EnableWebMvc自动配置就失效了；

 

 

 

 

 

 

添加这四个类

 

 

package com.atguigu.springboot.entities;

public class Department {

    private Integer id;
    private String departmentName;

    public Department() {
    }
    
    public Department(int i, String string) {
        this.id = i;
        this.departmentName = string;
    }

    public Integer getId() {
        return id;
    }

    public void setId(Integer id) {
        this.id = id;
    }

    public String getDepartmentName() {
        return departmentName;
    }

    public void setDepartmentName(String departmentName) {
        this.departmentName = departmentName;
    }

    @Override
    public String toString() {
        return "Department [id=" + id + ", departmentName=" + departmentName + "]";
    }
    
}

 

 

package com.atguigu.springboot.entities;

import java.util.Date;

public class Employee {

    private Integer id;
    private String lastName;

    private String email;
    //1 male, 0 female
    private Integer gender;
    private Department department;
    private Date birth;

    public Integer getId() {
        return id;
    }

    public void setId(Integer id) {
        this.id = id;
    }

    public String getLastName() {
        return lastName;
    }

    public void setLastName(String lastName) {
        this.lastName = lastName;
    }

    public String getEmail() {
        return email;
    }

    public void setEmail(String email) {
        this.email = email;
    }

    public Integer getGender() {
        return gender;
    }

    public void setGender(Integer gender) {
        this.gender = gender;
    }

    public Department getDepartment() {
        return department;
    }

    public void setDepartment(Department department) {
        this.department = department;
    }

    public Date getBirth() {
        return birth;
    }

    public void setBirth(Date birth) {
        this.birth = birth;
    }
    public Employee(Integer id, String lastName, String email, Integer gender,
                    Department department) {
        super();
        this.id = id;
        this.lastName = lastName;
        this.email = email;
        this.gender = gender;
        this.department = department;
        this.birth = new Date();
    }

    public Employee() {
    }

    @Override
    public String toString() {
        return "Employee{" +
                "id=" + id +
                ", lastName='" + lastName + '\'' +
                ", email='" + email + '\'' +
                ", gender=" + gender +
                ", department=" + department +
                ", birth=" + birth +
                '}';
    }
    
    
}

 

 

package com.atguigu.springboot.dao;

import java.util.Collection;
import java.util.HashMap;
import java.util.Map;

import com.atguigu.springboot.entities.Department;
import org.springframework.stereotype.Repository;



@Repository
public class DepartmentDao {

    private static Map<Integer, Department> departments = null;
    
    static{
        departments = new HashMap<Integer, Department>();
        
        departments.put(101, new Department(101, "D-AA"));
        departments.put(102, new Department(102, "D-BB"));
        departments.put(103, new Department(103, "D-CC"));
        departments.put(104, new Department(104, "D-DD"));
        departments.put(105, new Department(105, "D-EE"));
    }
    
    public Collection<Department> getDepartments(){
        return departments.values();
    }
    
    public Department getDepartment(Integer id){
        return departments.get(id);
    }
    
}

修改配置文件

 

 

添加方法

 

 

package com.atguigu.springboot.config;

import org.springframework.context.annotation.Bean;
import org.springframework.context.annotation.Configuration;
import org.springframework.web.bind.annotation.ResponseBody;
import org.springframework.web.servlet.config.annotation.EnableWebMvc;
import org.springframework.web.servlet.config.annotation.ViewControllerRegistry;
import org.springframework.web.servlet.config.annotation.WebMvcConfigurerAdapter;
//@EnableWebMvc
@Configuration
public class MyMvcConfig extends WebMvcConfigurerAdapter {
    @Override
    public void addViewControllers(ViewControllerRegistry registry){
        //浏览器发送 /atguigu 请求来到 success
        registry.addViewController("/atguigu").setViewName("success");
    }

    //所有的WebMvcConfigurerAdapter组件都会一起起作用
    @Bean //将组件注册在容器
    public WebMvcConfigurerAdapter webMvcConfigurerAdapter(){
        WebMvcConfigurerAdapter adapter = new WebMvcConfigurerAdapter() {
            @Override
            public void addViewControllers(ViewControllerRegistry registry){
                registry.addViewController("/").setViewName("login");
                registry.addViewController("/index.html").setViewName("index");
            }
        };
        return adapter;
    }
}

 

 

启动主程序

 

 

访问地址    http://localhost:8081/

 

 

 

6、国际化

 

 

                 步骤：
                       1）、编写国际化配置文件，抽取页面需要显示的国际化消息

                    

                        添加三个国际化配置文件

                     

 

 

 

 

 

 

 

 

 

 

 

 

 

 

 

 

 

 

 

 

 

 

 

 

 

 

 

 

 

 

 

 

 

2）、SpringBoot自动配置好了管理国际化资源文件的组件；

3）、去页面获取国际化的值；

 

 

 

修改编码方式

 

 

 

 

           原理：
             国际化Locale（区域信息对象）；LocaleResolver（获取区域信息对象）；

 

 

 

 

新增类

 

 

package com.atguigu.springboot.component;

import org.springframework.util.StringUtils;
import org.springframework.web.servlet.LocaleResolver;

import javax.servlet.http.HttpServletRequest;
import javax.servlet.http.HttpServletResponse;
import java.util.Locale;

/**
 * 可以在连接上携带区域信息
 * */
public class MyLocaleResolver implements LocaleResolver {
    @Override
    public Locale resolveLocale(HttpServletRequest request) {
        String l=request.getParameter("1");
        Locale locale=Locale.getDefault();
        if(!StringUtils.isEmpty(l)){
            String [] split = l.split("_");
            locale = new Locale(split[0],split[1]);
        }
        return locale;
    }

    @Override
    public void setLocale(HttpServletRequest request, HttpServletResponse response, Locale locale) {

    }


}

 

 

新增方法

 

 

 @Bean
    public LocaleResolver localeResolver(){
        return new MyLocaleResolver();
    }
