Swagger2是一个开源项目,用于为RESTful Web服务生成REST API文档。 它提供了一个用户界面,可通过Web浏览器访问RESTful Web服务。

要在Spring Boot应用程序中启用Swagger2,需要在构建配置文件中添加以下依赖项。

<dependency>
   <groupId>io.springfox</groupId>
   <artifactId>springfox-swagger2</artifactId>
   <version>2.7.0</version>
</dependency>
<dependency>
   <groupId>io.springfox</groupId>
   <artifactId>springfox-swagger-ui</artifactId>
   <version>2.7.0</version>
</dependency>
XML

对于Gradle用户,请在build.gradle 文件中添加以下依赖项。

compile group: ‘io.springfox‘, name: ‘springfox-swagger2‘, version: ‘2.7.0‘
compile group: ‘io.springfox‘, name: ‘springfox-swagger-ui‘, version: ‘2.7.0‘

现在,在主Spring Boot应用程序中添加@EnableSwagger2注释。 @EnableSwagger2注释用于为Spring Boot应用程序启用Swagger2。

主Spring Boot应用程序的代码如下所示 -

package com.yiibai.swaggerdemo;

import org.springframework.boot.SpringApplication;
import org.springframework.boot.autoconfigure.SpringBootApplication;
import springfox.documentation.swagger2.annotations.EnableSwagger2;

@SpringBootApplication
@EnableSwagger2
public class SwaggerDemoApplication {
   public static void main(String[] args) {
      SpringApplication.run(SwaggerDemoApplication.class, args);
   }
}
Java

接下来,创建Docket Bean以为Spring Boot应用程序配置Swagger2。需要定义一个基础包来为Swagger2配置REST API。

@Bean
public Docket productApi() {
      return new Docket(DocumentationType.SWAGGER_2).select()
         .apis(RequestHandlerSelectors.basePackage("com.yiibai.swaggerdemo")).build();
}
Java

现在,在主Spring Boot应用程序类文件中添加这个bean,主Spring Boot应用程序类看起来如下所示 -

package com.yiibai.swaggerdemo;

import org.springframework.boot.SpringApplication;
import org.springframework.boot.autoconfigure.SpringBootApplication;
import org.springframework.context.annotation.Bean;

import springfox.documentation.builders.RequestHandlerSelectors;
import springfox.documentation.spi.DocumentationType;
import springfox.documentation.spring.web.plugins.Docket;
import springfox.documentation.swagger2.annotations.EnableSwagger2;

@SpringBootApplication
@EnableSwagger2
public class SwaggerDemoApplication {
   public static void main(String[] args) {
      SpringApplication.run(SwaggerDemoApplication.class, args);
   }
   @Bean
   public Docket productApi() {
      return new Docket(DocumentationType.SWAGGER_2).select()
         .apis(RequestHandlerSelectors.basePackage("com.yiibai.swaggerdemo")).build();
   }
}
Java

现在,在构建配置文件中添加以下Spring Boot Starter Web依赖项以编写REST端点,如下所示 -

Maven用户可以在pom.xml 文件中添加以下依赖项 -

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

Gradle用户可以在build.gradle 文件中添加以下依赖项 -

compile(‘org.springframework.boot:spring-boot-starter-web‘)

现在,这里显示了在Rest Controller文件中构建两个简单的RESTful Web服务GET和POST的代码 -

package com.yiibai.swaggerdemo;

import java.util.ArrayList;
import java.util.List;

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

@RestController
public class SwaggerAPIController {
   @RequestMapping(value = "/products", method = RequestMethod.GET)
   public List<String> getProducts() {
      List<String> productsList = new ArrayList<>();
      productsList.add("Honey");
      productsList.add("Almond");
      return productsList;
   }
   @RequestMapping(value = "/products", method = RequestMethod.POST)
   public String createProduct() {
      return "Product is saved successfully";
   }
}
Java

完整的构建配置文件如下 -

Maven构建文件 - pom.xml 代码如下:

<?xml version = "1.0" encoding = "UTF-8"?>
<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>com.yiibai</groupId>
   <artifactId>swagger-demo</artifactId>
   <version>0.0.1-SNAPSHOT</version>
   <packaging>jar</packaging>
   <name>swagger-demo</name>
   <description>Demo project for Spring Boot</description>

   <parent>
      <groupId>org.springframework.boot</groupId>
      <artifactId>spring-boot-starter-parent</artifactId>
      <version>1.5.9.RELEASE</version>
      <relativePath /> <!-- lookup parent from repository -->
   </parent>

   <properties>
      <project.build.sourceEncoding>UTF-8</project.build.sourceEncoding>
      <project.reporting.outputEncoding>UTF-8</project.reporting.outputEncoding>
      <java.version>1.8</java.version>
   </properties>

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

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

      <dependency>
         <groupId>io.springfox</groupId>
         <artifactId>springfox-swagger2</artifactId>
         <version>2.7.0</version>
      </dependency>

      <dependency>
         <groupId>io.springfox</groupId>
         <artifactId>springfox-swagger-ui</artifactId>
         <version>2.7.0</version>
      </dependency>
   </dependencies>

   <build>
      <plugins>
         <plugin>
            <groupId>org.springframework.boot</groupId>
            <artifactId>spring-boot-maven-plugin</artifactId>
         </plugin>
      </plugins>
   </build>

</project>
XML

Gradle构建文件 - build.gradle -

buildscript {
   ext {
      springBootVersion = ‘1.5.9.RELEASE‘
   }
   repositories {
      mavenCentral()
   }
   dependencies {
      classpath("org.springframework.boot:spring-boot-gradle-plugin:${springBootVersion}")
   }
}
apply plugin: ‘java‘
apply plugin: ‘eclipse‘
apply plugin: ‘org.springframework.boot‘

group = ‘com.yiibai‘
version = ‘0.0.1-SNAPSHOT‘
sourceCompatibility = 1.8

repositories {
   mavenCentral()
} dependencies {
   compile(‘org.springframework.boot:spring-boot-starter-web‘)
   testCompile(‘org.springframework.boot:spring-boot-starter-test‘)
   compile group: ‘io.springfox‘, name: ‘springfox-swagger2‘, version: ‘2.7.0‘
   compile group: ‘io.springfox‘, name: ‘springfox-swagger-ui‘, version: ‘2.7.0‘
}

可以创建可执行的JAR文件,并使用以下Maven或Gradle命令运行Spring Boot应用程序。

对于Maven,可以使用以下命令 -

mvn clean install
Shell

在“BUILD SUCCESS”之后,可以在target目录下找到JAR文件。

对于Gradle,可以使用此命令 -

gradle clean build
Shell

在“BUILD SUCCESSFUL”之后,可以在build/libs目录下找到JAR文件。

现在,使用命令运行JAR文件 -

java –jar <JARFILE>

现在,应用程序将在Tomcat端口8080上启动。

现在,在Web浏览器URL => http://localhost:8080/swagger-ui.html , 并查看Swagger API功能,结果如下所示:
