Jersey2+swagger组建restful风格api及文档管理

1.jar包引入

        <dependency>
            <groupId>org.glassfish.jersey.core</groupId>
            <artifactId>jersey-server</artifactId>
        </dependency>
        <dependency>
            <groupId>io.swagger</groupId>
            <artifactId>swagger-jersey2-jaxrs</artifactId>
        </dependency>

        <dependency>
            <groupId>org.glassfish.jersey.containers</groupId>
            <artifactId>jersey-container-servlet</artifactId>
        </dependency>

        <dependency>
            <groupId>org.glassfish.jersey.inject</groupId>
            <artifactId>jersey-hk2</artifactId>
        </dependency>

        <dependency>
            <groupId>org.glassfish.jersey.media</groupId>
            <artifactId>jersey-media-json-jackson</artifactId>
        </dependency>

2.初始化Jersey、swagger

2.1 方式一 在web.xml中配置

初始化Jersey

<servlet>
        <servlet-name>Jersey REST Service</servlet-name>
        <servlet-class>org.glassfish.jersey.servlet.ServletContainer</servlet-class>
        <init-param>
            <param-name>jersey.config.server.provider.packages</param-name>
            <param-value>io.swagger.jaxrs.listing,com.baozh.api</param-value>
        </init-param>
        <load-on-startup>1</load-on-startup>
    </servlet>
    <servlet-mapping>
        <servlet-name>Jersey REST Service</servlet-name>
        <url-pattern>/api/*</url-pattern>
    </servlet-mapping>

初始化swagger，初始化url、版本信息、根目录，会提示“缺少mapping”错误，可以忽略

<servlet>
        <servlet-name>Jersey2Config</servlet-name>
        <servlet-class>io.swagger.jersey.config.JerseyJaxrsConfig</servlet-class>
        <init-param>
            <param-name>api.version</param-name>
            <param-value>1.0.0</param-value>
        </init-param>
        <init-param>
            <param-name>swagger.api.basepath</param-name>
            <param-value>http://localhost:8087/rest/api</param-value>
        </init-param>
        <load-on-startup>2</load-on-startup>
    </servlet>

2.2 方式二，通过application类+web.xml初始化swagger与Jersey

web.xml中servlet配置

<servlet>
        <servlet-name>Jersey REST Service</servlet-name>
        <servlet-class>org.glassfish.jersey.servlet.ServletContainer</servlet-class>
        <init-param>
            <param-name>javax.ws.rs.Application</param-name>
            <param-value>com.Jersey.config.SampleApplication</param-value>
        </init-param>
        <load-on-startup>1</load-on-startup>
    </servlet>
    <servlet-mapping>
        <servlet-name>Jersey REST Service</servlet-name>
        <url-pattern>/api/*</url-pattern>
    </servlet-mapping>

application类配置

public class SampleApplication extends Application {

    public SampleApplication() {
        BeanConfig beanConfig = new BeanConfig();
        beanConfig.setVersion("1.0.2");
        beanConfig.setSchemes(new String[]{"http"});
        beanConfig.setHost("localhost:8087");
        beanConfig.setBasePath("/rest/api");
        beanConfig.setResourcePackage("com.jersey.api");
        beanConfig.setScan(true);
    }
    @Override
    public Set<Class<?>> getClasses() {
        Set<Class<?>> resources = new HashSet();

        //api入口
        resources.add(ApiService.class);
        //json转换
        resources.add(JacksonFeature.class);
        resources.add(io.swagger.jaxrs.listing.ApiListingResource.class);
        resources.add(io.swagger.jaxrs.listing.SwaggerSerializers.class);

        return resources;
    }
}

3.加入swagger ui

将 https://github.com/swagger-api/swagger-ui中dist目录中的文件拷贝至项目api-docs目录中

拷贝ui文件并修改index.html 文件中url信息为工程的实际地址

访问http://localhost:8087/rest/api-docs即可看到swagger-ui信息

api请求效果
