2.34.2. SpringApplication

		
package cn.netkiller.swagger2;

import org.springframework.boot.SpringApplication;
import org.springframework.boot.autoconfigure.SpringBootApplication;

@SpringBootApplication
public class Application {

	public static void main(String[] args) {
		System.out.println("Swagger2!");
		SpringApplication.run(Application.class, args);
	}
}

2.34.3. EnableSwagger2

		
package cn.netkiller.swagger2;

import org.springframework.context.annotation.Bean;
import org.springframework.context.annotation.Configuration;

import com.google.common.base.Predicate;

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;
import static springfox.documentation.builders.PathSelectors.regex;
import static com.google.common.base.Predicates.or;

@Configuration
@EnableSwagger2
public class Swagger2Configuration {
	@Bean
	public Docket postsApi() {
		return new Docket(DocumentationType.SWAGGER_2).groupName("public").apiInfo(apiInfo()).select().paths(postPaths()).build();
	}

	private Predicate<String> postPaths() {
		return or(regex("/api/.*"), regex("/public/api/.*"));
	}

	private ApiInfo apiInfo() {
		return new ApiInfoBuilder().title("Open API").description("Open API reference for developers").termsOfServiceUrl("http://api.netkiller.cn").contact(new Contact("Neo Chen", "http://www.netkiller.cn", "netkiller@msn.com")).license("Mit License").licenseUrl("").version("1.0").build();
	}

}

2.34.4. RestController

		
package cn.netkiller.swagger2;

import org.springframework.web.bind.annotation.RequestMapping;
import org.springframework.web.bind.annotation.RequestMethod;
import org.springframework.web.bind.annotation.RestController;

@RestController
public class HelloController {

	@RequestMapping(method = RequestMethod.GET, value = "/api/hello")
	public String sayHello() {
		return "Swagger Hello World";
	}
}

2.34.5. @Api()

用於類；表示標識這個類是swagger的資源tags,value 是說明，可以使用tags替代, tags如果有多個值，生成多個list

		
@Api(value="用戶控製器",tags={"用戶操作介面"})
@RestController
public class UserController {

}

2.34.6. @ApiOperation()

用於方法；表示一個http請求的操作，value用於方法描述，notes用於提示內容，tags可以重新分組

		
@ApiImplicitParams() 請求參數，包含多個 @ApiImplicitParam 
@ApiImplicitParam()  
name–參數ming 
value–參數說明 
dataType–數據類型 
paramType–參數類型 
example–舉例說明

		
package cn.netkiller.swagger2;

import org.springframework.web.bind.annotation.RequestMapping;
import org.springframework.web.bind.annotation.RequestMethod;
import org.springframework.web.bind.annotation.RequestParam;
import org.springframework.web.bind.annotation.RestController;

import io.swagger.annotations.Api;
import io.swagger.annotations.ApiImplicitParam;
import io.swagger.annotations.ApiImplicitParams;
import io.swagger.annotations.ApiOperation;

@Api(value = "test", tags = "test")
@RestController
@RequestMapping("/api/test")
public class TestController {
	@ApiOperation(value = "介面說明", notes = "介面說明")
	@ApiImplicitParams({ @ApiImplicitParam(name = "id", value = "唯一ID", dataType = "Integer"), @ApiImplicitParam(name = "name", value = "名字") })
	@RequestMapping(value = "/name", method = { RequestMethod.GET, RequestMethod.POST })
	public String test(@RequestParam(value = "id", required = true) String id, @RequestParam(value = "name", required = true) String name) {
		return String.format("%s:%s", id, name);
	}
	
	@ApiOperation(value = "getGreeting", notes="get greeting",nickname = "getGreeting")
	@RequestMapping(method = RequestMethod.GET, value = "/api/javainuse")
	public <Hello> sayHello() {
		ArrayList<Hello> arrayList= new ArrayList<>();
			arrayList.add(new Hello());
		return arrayList;
	}

}

2.34.7. @ApiResponses

		
	@ApiOperation(value = "getGreeting", nickname = "getGreeting")
	@ApiResponses(value = {
		        @ApiResponse(code = 500, message = "Server error"),
		         @ApiResponse(code = 404, message = "Service not found"),
		        @ApiResponse(code = 200, message = "Successful retrieval",
		            response = Hello.class, responseContainer = "List") })
	@RequestMapping(method = RequestMethod.GET, value = "/api/javainuse")
	public <Hello> sayHello() {
			ArrayList<Hello> arrayList= new ArrayList<>();
			arrayList.add(new Hello());
		return arrayList;
	}

2.34.8. @ApiModel 實體類

		
@ApiModel()用於類 ；表示對類進行說明，用於參數用實體類接收 
value–表示對象名,description–描述,都可省略 

@ApiModelProperty()用於方法，欄位； 表示對model屬性的說明或者數據操作更改 
value 欄位說明 
name 重寫屬性名字 
dataType 重寫屬性類型 
required 是否必填 
example 舉例說明 
hidden 隱藏

		
package cn.netkiller.swagger2;

import java.io.Serializable;
import java.util.List;

import io.swagger.annotations.ApiModel;
import io.swagger.annotations.ApiModelProperty;

@ApiModel(value = "User", description = "通用用戶對象")
public class User implements Serializable {
	private static final long serialVersionUID = 1L;
	@ApiModelProperty(value = "用戶名", name = "username", example = "neo")
	private String username = "Neo";
	private String password = "passw0rd";
	private String nickname = "netkiller";
	@ApiModelProperty(value = "狀態", name = "state", example = "false", required = true)
	private boolean state = false;

	@ApiModelProperty(value = "字元串數組", hidden = true)
	private String[] array;
	private List<String> list;

	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;
	}

	public String getNickname() {
		return nickname;
	}

	public void setNickname(String nickname) {
		this.nickname = nickname;
	}

	public boolean isState() {
		return state;
	}

	public void setState(boolean state) {
		this.state = state;
	}

	public String[] getArray() {
		return array;
	}

	public void setArray(String[] array) {
		this.array = array;
	}

	public List<String> getList() {
		return list;
	}

	public void setList(List<String> list) {
		this.list = list;
	}

}

		
package cn.netkiller.swagger2;

import java.io.Serializable;
import java.util.List;

import org.springframework.web.bind.annotation.PostMapping;
import org.springframework.web.bind.annotation.RequestBody;
import org.springframework.web.bind.annotation.RestController;

import io.swagger.annotations.Api;
import io.swagger.annotations.ApiOperation;
import io.swagger.annotations.ApiParam;

@Api(value = "測試", tags = "test")
