本文详细介绍了Spring Boot如何支持Web开发，特别是如何处理JSON数据和请求参数。通过示例展示了如何创建RESTful服务，使用@RestController注解简化JSON响应，以及如何通过@RequestMapping接收POST请求。此外，还讲解了限制请求类型的方法，并演示了通过URL参数传递数据。
首先让大家快速认识Spring Boot 对基础Web开发所做的优化；接下来讲解了如何在SpringBoot中使用前端技术JSP、Thymeleaf，重点介绍了Thymeleaf的各种使用场景；后面几课介绍了如何使用Spring Boot 来构建RESTful服务、RESTful APIs，利用WebSocket双向通信的特性创建聊天室。
自从B/S架构（Browser/Server，浏览器/服务器模式）被发明以来，因为其具有跨平台、易移植、方便使用等特点，迅速地成为了技术架构的首选，前端Web 技术迅速发展起来。人们利用前端 Web技术构建各种应用场景，如电子商务平台、在线聊天室、后台管理系统等。页面技术也从最初的JSP演化为现在的模板引擎；信息交互由以前的XML发展到现在更流行的JSON；Spring Filter、loC、Aop等概念的发展更加方便人们构建Web系统。
Spring Boot 对Web开发的支持很全面，包括开发、测试和部署阶段都做了支持。spring-boot-starter-web是Spring Boot对Web开发提供支持的组件，主要包括RESTful，参数校验、使用Tomcat作为内嵌容器等功能，接下来给大家一一介绍。
JSON的支持
JSON（JavaScript Object Notation）是一种轻量级的数据交换格式，易于阅读和编写，同时也易于机器解析和生成。JSON采用完全独立于语言的文本格式，但是也使用了类似于C语言家族的习惯（包括C、C++、C#、Java、JavaScript、Perl、Python等），这些特性使JSON成为理想的数据交换语言。
早期人们习惯使用XML进行信息交互，后来JSON的使用更加简单，到了现在信息交互大部分都以JSON为主。早期在Spring体系中使用JSON还比较复杂，需要配置多项XML和注解，现在在Spring Boot体系中，对JSON支持简单而又完善，在Web层使用仅仅只需要一个注解即可完成。接下来使用案例说明。
新建一个spring-boot-web项目，在pom.xml中添加Web依赖。
<dependencies>
<dependency>
<groupId>org.springframework.boot</groupId>
<artifactId>spring-boot-starter-web</artifactId>
</dependency>
<dependency>
<groupId>org.springframework.boot</groupId>
<artifactId>spring-boot-devtools</artifactId>
<scope>runtime</scope>
</dependency>
<dependency>
<groupId>org.springframework.boot</groupId>
<artifactId>spring-boot-starter-test</artifactId>
<scope>test</scope>
</dependency>
</dependencies>启动类:
package com.neo;
import org.springframework.boot.SpringApplication;
import org.springframework.boot.autoconfigure.SpringBootApplication;
@SpringBootApplication
public class WebApplication {
public static void main(String[] args) {
SpringApplication.run(WebApplication.class, args);
}
}
在项目根路路径下新建 model 包，在包下新建一个实体类 User，User 信息如下：
package com.neo.model;
import org.hibernate.validator.constraints.Length;
import javax.validation.constraints.Max;
import javax.validation.constraints.Min;
import javax.validation.constraints.NotEmpty;
public class User {
@NotEmpty(message="姓名不能为空")
private String name;
@Max(value = 100, message = "年龄不能大于100岁")
@Min(value= 18 ,message= "必须年满18岁！" )
private int age;
@NotEmpty(message="密码不能为空")
@Length(min=6,message="密码长度不能小于6位")
private String pass;
public String getName() {
return name;
}
public void setName(String name) {
this.name = name;
}
public int getAge() {
return age;
}
public void setAge(int age) {
this.age = age;
}
public String getPass() {
return pass;
}
public void setPass(String pass) {
this.pass = pass;
}
@Override
public String toString() {
return ("name=" + this.name + ",age=" + this.age + ",pass=" + this.pass);
}
}
在项目中新建 Web 包，并在 Web 包下新建⼀一个类 WebController，在类中创建⼀一个方法返回 User，如下：
@RestController
public class WebController {
@RequestMapping(name="/getUser", method= RequestMethod.POST)
public User getUser() {
User user=new User();
user.setName("⼩小明");
user.setAge(12);
user.setPass("123456");
return user;
}
}@RestController 注解相当于@ResponseBody+@Controller合在一起的作用，如果Web层的类上使用了@RestController注解，就代表这个类中所有的方法都会以JSON的形式返回结果，也相当于JSON的一种快捷使用方式；
@RequestMapping（name="/getUser"，method=RequestMethod.POST），以/getUser的方式去请求，method=RequestMethod.POST 是指只可以使用Post的方式去请求，如果使用Get的方式去请求的话，则会报405不允许访问的错误。
在 test 包下新建 WebControllerTest 测试类，对 getUser() ⽅方法进行测试。
@SpringBootTest
public class WebControllerTest {
//省略略部分代码
@Test
public void getUser() throws Exception {
String responseString = mockMvc.perform(MockMvcRequestBuilders.post("/getU
ser"))
.andReturn().getResponse().getContentAsString();
System.out.println("result : "+responseString);
}
}这里的测试代码和上面的稍有区别，“.andReturn().getResponse().getContentAsString(); ”的意思是获取请求的返回信息，并将返回信息转换为字符串，最后将请求的响应结果打印出来。执⾏完 Test，返回结果如下：

说明 Spring Boot 自动将 User 对象转成了 JSON 进行返回。那么如果返回的是一个 list 呢，在WebController 添加⽅法 getUsers()，代码如下：
@RequestMapping("/getUsers")
public List<User> getUsers() {
List<User> users=new ArrayList<User>();
User user1=new User();
user1.setName("neo");
user1.setAge(30);
user1.setPass("neo123");
users.add(user1);
User user2=new User();
user2.setName("⼩小明");
user2.setAge(12);
user2.setPass("123456");
users.add(user2);
return users;
}添加测试方法：
@Test
public void getUsers() throws Exception {
String responseString = mockMvc.perform(MockMvcRequestBuilders.get("/getUsers"
))
.andReturn().getResponse().getContentAsString();
System.out.println("result : "+responseString);

说明不管是对象还是集合或者对象嵌套，Spring Boot 均可以将其转换为JSON字符串，这种方式特别适合系统提供接口时使用。
请求传参
请求传参是Web开发最基础的内容，前端浏览器和后端服务器正是依赖交互过程中的参数，来判断用户是否登录、用户正在执行时哪些动作，因此参数的传递和接收是一个Web系统最基础的功能。Spring Boot内置了很多种参数接收方式，提供一些注解来帮助限制请求的类型、接收不同格式的参数等，接下来我们举例介绍。
使用Spring Boot 可以轻松的对请求做一些限制，比如为了安全我们只允许POST请求的访问，只需要在方法上添加一个配置既可：
@RequestMapping(value="/getUser", method= RequestMethod.GET)
public User getUser() {
User user=new User();
user.setName("小明");
user.setAge(12);
user.setPass("123456");
return user;
}这时候再以 GET 请求去访问，就会返回如下结果：
从返回的结果可以看出，根本没有返回任何信息。
如果要求其请求只支持GET请求，method 设置为：method=RequestMethod.GET；如果不进行设置默认两种方式的请求都支持。
Spring Web层支持多种方法传参，在上一节中我们传入一个属性name，直接使用对象接收也可以支持。
@RequestMapping(name="/getUser", method= RequestMethod.POST)
public String getUser(User user) {
...
}这样的写法，只要是 User 的属性都会被自动填充到 User 对象中；还有另外一种传参的方式，使用 URL 进行传参，这种形式的传参地址栏会更更加美观一些。
@RequestMapping(value="get/{name}", method=RequestMethod.GET)
public String get(@PathVariable String name) {
return name;
}在浏览器器中输入网址：http://localhost:8080/get/neo，返回：neo，说明 name 值已经成功传入。
