??knife4j是為集成Swagger生成api文檔的增強(qiáng)解決方案特石，前后端Java代碼以及前端Ui模塊進(jìn)行分離,在微服務(wù)架構(gòu)下使用更加靈活盅蝗，
提供專注于Swagger的增強(qiáng)解決方案,不同于只是改善增強(qiáng)前端Ui部分，我們這里使用knife4j作為文檔管理工具來代替swagger-ui姆蘸。
1墩莫、在GitEgg-Platform工程下新建gitegg-platform-swagger子工程，在GigEgg-Platform中的子工程gitegg-platform-bom中逞敷，修改pom
.xml狂秦，以maven bom的方式使用knife4j:
<!-- Swagger2 knife4j bom方式引入 -->
<dependency>
<groupId>com.github.xiaoymin</groupId>
<artifactId>knife4j-dependencies</artifactId>
<version>${knife4j.version}</version>
<type>pom</type>
<scope>import</scope>
</dependency>
2、在gitegg-platform-swagger子工程中的pom.xml添加knife4j引用：
<?xml version="1.0" encoding="UTF-8"?>
<project xmlns="http://maven.apache.org/POM/4.0.0"
xmlns:xsi="http://www.w3.org/2001/XMLSchema-instance"
xsi:schemaLocation="http://maven.apache.org/POM/4.0.0 http://maven.apache.org/xsd/maven-4.0.0.xsd">
<parent>
<artifactId>GitEgg-Platform</artifactId>
<groupId>com.gitegg.platform</groupId>
<version>1.0-SNAPSHOT</version>
</parent>
<modelVersion>4.0.0</modelVersion>
<artifactId>gitegg-platform-swagger</artifactId>
<name>${project.artifactId}</name>
<version>${project.parent.version}</version>
<packaging>jar</packaging>
<dependencies>
<dependency>
<groupId>com.github.xiaoymin</groupId>
<artifactId>knife4j-spring-boot-starter</artifactId>
</dependency>
</dependencies>
</project>
3推捐、在gitegg-platform-swagger子工程中新建SwaggerConfig.java文件：
package com.gitegg.platform.swagger.config;
import com.github.xiaoymin.knife4j.spring.annotations.EnableKnife4j;
import org.springframework.context.annotation.Bean;
import org.springframework.context.annotation.Configuration;
import org.springframework.context.annotation.Import;
import springfox.bean.validators.configuration.BeanValidatorPluginsConfiguration;
import springfox.documentation.builders.ApiInfoBuilder;
import springfox.documentation.builders.PathSelectors;
import springfox.documentation.builders.RequestHandlerSelectors;
import springfox.documentation.service.ApiInfo;
import springfox.documentation.spi.DocumentationType;
import springfox.documentation.spring.web.plugins.Docket;
import springfox.documentation.swagger2.annotations.EnableSwagger2;
@Configuration
@EnableSwagger2
@EnableKnife4j
@Import(BeanValidatorPluginsConfiguration.class)
public class SwaggerConfig {
@Bean(value = "GitEggApi")
public Docket GitEggApi() {
Docket docket=new Docket(DocumentationType.SWAGGER_2)
.apiInfo(apiInfo())
//分組名稱
.groupName("2.X版本")
.select()
//這里指定Controller掃描包路徑
.apis(RequestHandlerSelectors.basePackage("com.gitegg.*.*.controller"))
.paths(PathSelectors.any())
.build();
return docket;
}
private ApiInfo apiInfo() {
return new ApiInfoBuilder().version("1.0.0")
.title("Spring Cloud Swagger2 文檔")
.description("Spring Cloud Swagger2 文檔")
.termsOfServiceUrl("www.gitegg.com")
.build();
}
}
4裂问、在gitegg-service工程中引入gitegg-platform-swagger
<?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">
<parent>
<artifactId>GitEgg-Cloud</artifactId>
<groupId>com.gitegg.cloud</groupId>
<version>1.0-SNAPSHOT</version>
</parent>
<modelVersion>4.0.0</modelVersion>
<artifactId>gitegg-service</artifactId>
<packaging>pom</packaging>
<modules>
<module>gitegg-service-base</module>
<module>gitegg-service-bigdata</module>
<module>gitegg-service-system</module>
</modules>
<dependencies>
<!-- gitegg數(shù)據(jù)庫驅(qū)動(dòng)及連接池 -->

<!-- gitegg swagger2-knife4j -->

<!-- spring boot 健康監(jiān)控 -->
<dependency>
<groupId>org.springframework.boot</groupId>
<artifactId>spring-boot-starter-actuator</artifactId>
</dependency>
</dependencies>
</project>
5、在gitegg-service-system工程下的SystemController.java類里面添加Swagger2相關(guān)注解
package com.gitegg.service.system.controller;
import com.gitegg.service.system.service.ISystemService;
import io.swagger.annotations.Api;
import io.swagger.annotations.ApiOperation;
import lombok.AllArgsConstructor;
import org.springframework.web.bind.annotation.GetMapping;
import org.springframework.web.bind.annotation.RequestMapping;
import org.springframework.web.bind.annotation.RestController;
@RestController
@RequestMapping(value = "system")
@AllArgsConstructor
@Api(tags = "gitegg-system")
public class SystemController {
private final ISystemService systemService;
@GetMapping(value = "list")
@ApiOperation(value = "system list接口")
public Object list() {
return systemService.list();
}
@GetMapping(value = "page")
@ApiOperation(value = "system page接口")
public Object page() {
return systemService.page();
}
}
6玖姑、GitEggSystemApplication.java加入組件掃描的注解愕秫，讓Spring在啟動(dòng)的時(shí)候加載到swagger2的配置:
package com.gitegg.service.system;
import org.mybatis.spring.annotation.MapperScan;
import org.springframework.boot.SpringApplication;
import org.springframework.boot.autoconfigure.SpringBootApplication;
import org.springframework.context.annotation.ComponentScan;
/**
* gitegg-system 啟動(dòng)類
*/
@ComponentScan(basePackages = "com.gitegg")
@MapperScan("com.gitegg.*.*.mapper")
@SpringBootApplication
public class GitEggSystemApplication {
public static void main(String[] args) {
SpringApplication.run(GitEggSystemApplication.class,args);
}
}
7、運(yùn)行g(shù)itegg-service-system焰络，打開瀏覽器訪問：http://127.0.0.1:8001/doc.html戴甩，可以看到swagger2文檔界面
