2.在项目中使用Swagger需要springfox
(1)springfox swagger2
(2)springfox swagger UI
三.SpringBoot集成Swagger
1.步骤:
-
建立一个Springboot带Spring MVC的项目
-
导入两个依赖swagger2和swaggerUI
-
编写一个HelloController测试项目是否可以正常运行(略)
-
编写config配置Swagger
-
测试运行
2.新建SpringBoot的web项目
3.导入两个依赖swagger2和swaggerUI
<dependency> <groupId>io.springfox</groupId> <artifactId>springfox-swagger2</artifactId> <version>2.9.2</version> </dependency> <dependency> <groupId>io.springfox</groupId> <artifactId>springfox-swagger-ui</artifactId> <version>2.9.2</version> </dependency>
4.编写config配置Swagger
import org.springframework.context.annotation.Configuration; import springfox.documentation.swagger2.annotations.EnableSwagger2; @Configuration @EnableSwagger2 //开启Swagger2 public class SwaggerConfig { }
5.测试运行
-
http://localhost:8080/swagger-ui.html
四.配置Swagger信息
import org.springframework.context.annotation.Bean; import org.springframework.context.annotation.Configuration; 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 java.util.ArrayList; @Configuration @EnableSwagger2 //开启Swagger2 public class SwaggerConfig { //配置Swagger的Docker的bean实例 @Bean public Docket docket() { return new Docket(DocumentationType.SWAGGER_2) .apiInfo(apiInfo()); } //配置Swagger信息 private ApiInfo apiInfo() { //作者信息 Contact contact = new Contact("wzh", "https://www.cnblogs.com/zhihaospace/", "464407764@qq.com"); return new ApiInfo( "WZH的Swagger Api文档", "Api 文档", "1.0", "https://www.cnblogs.com/zhihaospace/", contact, "Apache 2.0", "http://www.apache.org/licenses/LICENSE-2.0", new ArrayList() ); } }
五.配置Swagger扫描接口
-
enable:通过springboot配置文件来配置是否显示spring-ui.html页面,注意端口号
-
apis:配置需要扫描的路径
-
paths:配置过滤掉的路径
import org.springframework.context.annotation.Bean; import org.springframework.context.annotation.Configuration; import org.springframework.core.env.Environment; import org.springframework.core.env.Profiles; import springfox.documentation.builders.RequestHandlerSelectors; 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 java.util.ArrayList; @Configuration @EnableSwagger2 //开启Swagger2 public class SwaggerConfig { //配置Swagger的Docker的bean实例 @Bean public Docket docket(Environment environment) { //配置 在dev或test生产环境下可以显示swagger环境,release环境下看不到Swagger Profiles profiles = Profiles.of("dev","test"); //通过environment.acceptsProfiles判断是否处在设定的环境中 boolean flag = environment.acceptsProfiles(profiles); return new Docket(DocumentationType.SWAGGER_2) .apiInfo(apiInfo()) //enable 配置是否启用Swagger,为false则swagger-ui页面不能在浏览器中访问 .enable(flag) .select() /* * RequestHandlerSelectors 配置要扫描接口的方式 * 参数: * basePackage("ustc.wzh.swagger") 指定要扫描的包 * withClassAnnotation(RestController.class) 扫描类上的注解,参数是一个类注解的反射对象 * withMethodAnnotation(GetMapping.class) 扫描方法上的注解,参数是一个方法注解的反射对象 * any() 扫描全部 * none() 不扫描 */ .apis(RequestHandlerSelectors.basePackage("ustc.wzh.swagger")) /* * paths 过滤路径(就是不去扫描的路径) * any() 全部过滤 * none() 不过滤 * regex(/[a-z]/) 过滤到正则表达式代表的路径 * ant("xxx") 指定路径过滤 */ //.paths(PathSelectors.ant("/wzh/**")) .build() ; } //配置Swagger信息 private ApiInfo apiInfo() { //作者信息 Contact contact = new Contact("wzh", "https://www.cnblogs.com/zhihaospace/", "464407764@qq.com"); return new ApiInfo( "WZH的Swagger Api文档", "Api 文档", "1.0", "https://www.cnblogs.com/zhihaospace/", contact, "Apache 2.0", "http://www.apache.org/licenses/LICENSE-2.0", new ArrayList() ); } }
六.配置API文档的分组
1.使用groupName方法设置即可
.groupName("WZH")
2.配置多个分组
-
只需要多课Docket实例即可
@Bean public Docket docket1(){ return new Docket(DocumentationType.SWAGGER_2).groupName("AAA"); } @Bean public Docket docket2(){ return new Docket(DocumentationType.SWAGGER_2).groupName("BBB"); } @Bean public Docket docket3(){ return new Docket(DocumentationType.SWAGGER_2).groupName("CCC"); }
七.实体类
-
如果我们的接口中返回值存在的实体类,则这个实体类就会被扫描到Swagger中
-
我们增加了@ApiModel和@ApiModelProperty注解就会在Swagger-ui中扫描到
import io.swagger.annotations.ApiModel; import io.swagger.annotations.ApiModelProperty; @ApiModel("用户实体类") public class User { @ApiModelProperty("用户名") public String username; @ApiModelProperty("密码") public String password; public User(String username, String password) { this.username = username; this.password = password; } }
八.Controller中使用
-
最重要的是测试功能,此时我们在控制器中故意写除零操作导致错误,Swagger会显示Response错误的详细详细内容
import io.swagger.annotations.ApiOperation; import io.swagger.annotations.ApiParam; import org.springframework.web.bind.annotation.GetMapping; import org.springframework.web.bind.annotation.PostMapping; import org.springframework.web.bind.annotation.RestController; import ustc.wzh.swagger.pojo.User; @RestController public class HelloController { @GetMapping(value = "/hello") public String hello(){ return "hello"; } @ApiOperation("获得user") @PostMapping(value = "/user") public User user(@ApiParam("用户名") String username,@ApiParam("密码") String password){ int i = 5/0; return new User(username,password); } }
