swagger对应后端开发而言，几乎就是一个神器，调试后端api接口非常好用的工具，我们项目是分布式微服务架构，利用Spring Cloud技术，那么如何在java项目中配置好，分为下面几个步骤：  
1、在独自的服务模块启动类中加载  
以下是启动数据库连接、FeignClientConfig、CommonConfig、SwaggerConfig等整体服务信息。

package xxxxx.test;
    
    import com.fasterxml.jackson.annotation.JsonAutoDetect;
    import com.fasterxml.jackson.annotation.PropertyAccessor;
    import com.fasterxml.jackson.databind.ObjectMapper;
    import com.github.pagehelper.PageHelper;
    
    import org.apache.curator.framework.CuratorFramework;
    import org.apache.curator.framework.recipes.leader.LeaderLatch;
    import org.springframework.amqp.rabbit.annotation.EnableRabbit;
    import org.springframework.beans.factory.annotation.Autowired;
    import org.springframework.beans.factory.annotation.Value;
    import org.springframework.boot.SpringApplication;
    import org.springframework.boot.autoconfigure.SpringBootApplication;
    import org.springframework.boot.web.servlet.FilterRegistrationBean;
    import org.springframework.cache.annotation.EnableCaching;
    import org.springframework.cloud.client.discovery.EnableDiscoveryClient;
    import org.springframework.cloud.netflix.feign.EnableFeignClients;
    import org.springframework.context.MessageSource;
    import org.springframework.context.annotation.Bean;
    import org.springframework.context.annotation.ComponentScan;
    import org.springframework.context.annotation.EnableAspectJAutoProxy;
    import org.springframework.context.annotation.FilterType;
    import org.springframework.context.support.ResourceBundleMessageSource;
    import org.springframework.data.redis.connection.RedisConnectionFactory;
    import org.springframework.data.redis.core.RedisTemplate;
    import org.springframework.data.redis.core.StringRedisTemplate;
    import org.springframework.data.redis.serializer.Jackson2JsonRedisSerializer;
    import org.springframework.data.redis.serializer.RedisSerializer;
    import org.springframework.data.redis.serializer.StringRedisSerializer;
    import org.springframework.integration.annotation.IntegrationComponentScan;
    import org.springframework.security.config.annotation.method.configuration.EnableGlobalMethodSecurity;
    import org.springframework.session.web.http.CookieSerializer;
    import org.springframework.session.web.http.DefaultCookieSerializer;
    
    import java.util.ArrayList;
    import java.util.HashMap;
    import java.util.Map;
    import java.util.Properties;
    import java.util.UUID;
    
    /**
     * Created by zhangsan on 2017/4/11.
     */
    @SpringBootApplication
    @ComponentScan(value = {"xxxx.*"},
            excludeFilters = {@ComponentScan.Filter(type = FilterType.REGEX,pattern = {"xxxxx.order.*","xxxx.common.base.*"})})
    @EnableAspectJAutoProxy
    @EnableDiscoveryClient
    @EnableGlobalMethodSecurity(securedEnabled = true, prePostEnabled = true)
    @IntegrationComponentScan
    @EnableFeignClients
    @EnableCaching
    @EnableRabbit
    public class PscmQualityTestApplication {
    
    
        @Value("${leaderLatch.index}")
        private String leaderLatchIndex;
    
    
        public static void main(String[] args) {
            Object[] sources = {PscmQualityTestApplication.class, DataSourceConfig.class, FeignClientConfig.class, SwaggerConfig.class, HttpSessionConfig.class, CommonConfig.class, SecurityConfig.class};
            SpringApplication.run(sources, args);
        }

2、上面的启动类包括了Swagger工具配置类：

package test;
    
    import org.springframework.context.annotation.Bean;
    import org.springframework.context.annotation.Configuration;
    import org.springframework.context.annotation.Profile;
    import springfox.documentation.builders.PathSelectors;
    import springfox.documentation.builders.RequestHandlerSelectors;
    import springfox.documentation.spi.DocumentationType;
    import springfox.documentation.spring.web.plugins.Docket;
    import springfox.documentation.swagger2.annotations.EnableSwagger2;
    
    /**
     * Created by zhangsan on 2017/8/10.
     */
    @Configuration
    @Profile("!production")
    @EnableSwagger2
    public class SwaggerConfig {
    
        @Bean
        public Docket api() {
            return new Docket(DocumentationType.SWAGGER_2)
                    .select()
                    .apis(RequestHandlerSelectors.basePackage("aa.bb.cc"))//扫描aa.bb.cc路径下的所有
                    .paths(PathSelectors.any())
                    .build();
        }
    }

3、在pom文件中，引入依赖的jar包：  
第一个引入swagge核心的jar包，第二个引入swagger的UI

<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>

4、启动服务成功  
5、访问服务中的所有api接口
