Spring Boot - 启用Swagger2 Spring Boot - 管理客户端 Spring Boot - 创建Docker镜像 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浏览器访问我们的RESTful Web服务。 要在Spring Boot应用程序中启用Swagger2,您需要在我们的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> 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。 主要Spring Boot应用程序的代码如下所示 package com.codingdict.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); } } 接下来,创建Docket Bean以为Spring Boot应用程序配置Swagger2。我们需要定义基础包来为Swagger2配置REST API。 @Bean public Docket productApi() { return new Docket(DocumentationType.SWAGGER_2).select() .apis(RequestHandlerSelectors.basePackage("com.codingdict.swaggerdemo")).build(); } 现在,在主Spring Boot应用程序类文件中添加这个bean,你的主Spring Boot应用程序类看起来如下所示 package com.codingdict.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.codingdict.swaggerdemo")).build(); } } 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> 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.codingdict.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"; } } 完整的构建配置文件如下 Maven - pom.xml <?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.codingdict</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> Gradle - 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.codingdict' 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' } 您可以创建可执行的JAR文件,并使用以下Maven或Gradle命令运行Spring Boot应用程序。 对于Maven,您可以使用此处显示的命令 mvn clean install 在“BUILD SUCCESS”之后,您可以在目标目录下找到JAR文件。 对于Gradle,您可以使用此处显示的命令 gradle clean build 在“BUILD SUCCESSFUL”之后,您可以在build / libs目录下找到JAR文件。 现在,使用此处显示的命令运行JAR文件 java –jar <JARFILE> 现在,应用程序将在Tomcat端口8080上启动,如图所示 现在,点击Web浏览器中的URL并查看Swagger API功能。 http://localhost:8080/swagger-ui.html Spring Boot - 管理客户端 Spring Boot - 创建Docker镜像
