Swagger:实现前后端分离开发
使用IDEA创建一个web项目

在pom.xml中添加swagger-api依赖

添加SwaggerConfig和WebMvcConfig配置类
package com.uos.demo.config;
import org.springframework.context.annotation.Bean;
import org.springframework.context.annotation.ComponentScan;
import org.springframework.context.annotation.Configuration;
import org.springframework.web.servlet.config.annotation.EnableWebMvc;
import springfox.documentation.builders.ApiInfoBuilder;
import springfox.documentation.service.ApiInfo;
import springfox.documentation.service.Contact;
import springfox.documentation.spi.DocumentationType;
import springfox.documentation.spring.web.plugins.Docket;
import springfox.documentation.swagger2.annotations.EnableSwagger2;
@Configuration//必须存在
@EnableSwagger2//必须存在
@EnableWebMvc//必须存在
//必须存在扫描的API Controller包
@ComponentScan(basePackages ={"com.uos.demo.controller"})
public class SwaggerConfig{
@Bean
public Docket customDocket(){
return new Docket(DocumentationType.SWAGGER_2).apiInfo(apiInfo());
}
private ApiInfo apiInfo(){
Contact contact= new Contact("太子殿下","https://www.cnblogs.com/my-program-life/","3466614871@qq.com");
return new ApiInfoBuilder()
.title("项目API接口")
.description("API接口")
.contact(contact).version("1.1.0")
.build();
}
}
package com.uos.demo.config;
import org.springframework.context.annotation.Configuration;
import org.springframework.web.servlet.config.annotation.ResourceHandlerRegistry;
import org.springframework.web.servlet.config.annotation.WebMvcConfigurer;
@Configuration
class WebMvcConfig implements WebMvcConfigurer {
public void addResourceHandlers(ResourceHandlerRegistry registry) {
registry.addResourceHandler("swagger-ui.html")
.addResourceLocations("classpath:/META-INF/resources/");
registry.addResourceHandler("/webjars/**")
.addResourceLocations("classpath:/META-INF/resources/webjars/");
}
}
创建User类
package com.uos.demo.pojo;
/*
用户类
*/
public class User {
private String username;
private String password;
public User() {
}
public User(String username, String password) {
this.username = username;
this.password = password;
}
public String getUsername() {
return username;
}
public void setUsername(String username) {
this.username = username;
}
public String getPassword() {
return password;
}
public void setPassword(String password) {
this.password = password;
}
}
创建UserController类
package com.uos.demo.controller;
import com.uos.demo.pojo.User;
import io.swagger.annotations.Api;
import io.swagger.annotations.ApiImplicitParam;
import io.swagger.annotations.ApiOperation;
import org.springframework.web.bind.annotation.*;
import java.util.ArrayList;
import java.util.HashMap;
import java.util.List;
import java.util.Map;
@RestController
@Api(value = "用户模块",description = "用户模块的接口信息")
public class UserController {
//模拟数据库
public static List<User> users = new ArrayList<>();
static {
users.add(new User("张三","123456"));
users.add(new User("李四","1234"));
}
//获取用户列表的方法
@GetMapping("/users")
@ApiOperation(value = "获取用户列表",notes = "获取所有用户的列表信息")
public Object users(){
Map<String,Object> map = new HashMap<>();
map.put("users",users);
return map;
}
//通过id来进行查询用户的信息
@ApiOperation(value = "获取单个用户",notes = "根据id查询某个用户的信息")
@ApiImplicitParam(value = "用户的id",paramType = "path")
@GetMapping("/users/{id}")
public User getUserById(@PathVariable("id") int id){
return users.get(id);
}
//添加用户
@ApiOperation(value = "添加用户",notes = "根据用户传入的信息添加用户")
@ApiImplicitParam(value = "用户对象",paramType = "query")
@PostMapping("/user")
public Object add(User user){
return users.add(user);
}
//删除用户
@ApiOperation(value = "删除用户",notes = "根据用户传入的id删除用户")
@ApiImplicitParam(value = "用户id",paramType = "path")
@DeleteMapping("/user/{id}")
public Object delete(@PathVariable("id") int id){
return users.remove(id);
}
}
创建SpringBoot启动类
package com.uos;
import org.springframework.boot.SpringApplication;
import org.springframework.boot.autoconfigure.SpringBootApplication;
import org.springframework.web.servlet.config.annotation.EnableWebMvc;
@SpringBootApplication
@EnableWebMvc
public class SwaggerDemoApplication {
public static void main(String[] args) {
SpringApplication.run(SwaggerDemoApplication.class, args);
}
}
