这里写自定义目录标题

dubbo2.7+包名从com.alibaba换成了org.apache。https://github.com/Sayi/swagger-dubbo 的version2.0.1 不兼容dubbo2.7+，包中引用了是dubbo2.6包。
dubbo2.7集成swagger，需要将swagger-dubbo2.0.1中类引用修改下，还需将ReferenceManager类中contexts改为大写CONTEXTS

原配置：

<dependency>
<groupId>io.swagger</groupId>
<artifactId>swagger-core</artifactId>
<version>1.5.16</version>
</dependency>

<dependency>
<groupId>com.alibaba</groupId>
<artifactId>dubbo</artifactId>
<version>2.6.0</version>
<scope>provided</scope>
<exclusions>
<exclusion>
<groupId>org.springframework</groupId>
<artifactId>spring</artifactId>
</exclusion>
</exclusions>
</dependency>

修改后

<dependency>
<groupId>io.swagger</groupId>
<artifactId>swagger-core</artifactId>
<version>1.5.20</version>
</dependency>

<dependency>
<groupId>org.apache.dubbo</groupId>
<artifactId>dubbo</artifactId>
<version>2.7.0</version>
<scope>provided</scope>
<exclusions>
<exclusion>
<groupId>org.springframework</groupId>
<artifactId>spring</artifactId>
</exclusion>
</exclusions>
</dependency>

DubboPropertyConfig类
import com.alibaba.dubbo.config.ApplicationConfig;
改为
import org.apache.dubbo.config.ApplicationConfig;

ReferenceManager类
import com.alibaba.dubbo.config.ApplicationConfig;
import com.alibaba.dubbo.config.ReferenceConfig;
import com.alibaba.dubbo.config.spring.ServiceBean;
import com.alibaba.dubbo.config.spring.extension.SpringExtensionFactory;
改为
import org.apache.dubbo.config.ApplicationConfig;
import org.apache.dubbo.config.ReferenceConfig;
import org.apache.dubbo.config.spring.ServiceBean;
import org.apache.dubbo.config.spring.extension.SpringExtensionFactory;

public Object getProxy(String interfaceClass) {
Set<Entry<Class<?>, Object>> entrySet = interfaceMapProxy.entrySet();
for (Entry<Class<?>, Object> entry : entrySet) {
if (entry.getKey().getName().equals(interfaceClass)) { return entry.getValue(); }
}

for (ServiceBean<?> service : services) {
if (interfaceClass.equals(service.getInterfaceClass().getName())) {
ReferenceConfig<Object> reference = new ReferenceConfig<Object>();
reference.setApplication(service.getApplication());
reference.setRegistry(service.getRegistry());
reference.setRegistries(service.getRegistries());
reference.setInterface(service.getInterfaceClass());
reference.setVersion(service.getVersion());
interfaceMapProxy.put(service.getInterfaceClass(), reference.get());
return reference.get();
}
}
return null;
}

改为

public Object getProxy(String interfaceClass) {
Set<Entry<Class<?>, Object>> entrySet = interfaceMapProxy.entrySet();
for (Entry<Class<?>, Object> entry : entrySet) {
if (entry.getKey().getName().equals(interfaceClass)) { return entry.getValue(); }
}

for (ServiceBean<?> service : services) {
if (interfaceClass.equals(service.getInterfaceClass().getName())) {
ReferenceConfig<Object> reference = new ReferenceConfig<Object>();
reference.setApplication(service.getApplication());
reference.setRegistry(service.getRegistry());
reference.setRegistries(service.getRegistries());
reference.setInterface(service.getInterfaceClass());

reference.setVersion(service.getVersion());
reference.setGroup(service.getGroup());
reference.setRetries(service.getRetries());
reference.setActives(service.getActives());
reference.setCache(service.getCache());
// 集群方式
reference.setCluster(service.getCluster());
reference.setLayer(service.getLayer());
reference.setTimeout(service.getTimeout());
reference.setConnections(service.getConnections());
// 负载均衡策略
reference.setLoadbalance(service.getLoadbalance());
interfaceMapProxy.put(service.getInterfaceClass(), reference.get());
return reference.get();
}
}
return null;
}

最重要的是：ReferenceManager类中
Field field = SpringExtensionFactory.class.getDeclaredField(“contexts”);
改为
Field field = SpringExtensionFactory.class.getDeclaredField(“CONTEXTS”);

然后将项目打包，按照https://github.com/Sayi/swagger-dubbo的配置
简单修改后：https://github.com/hjnjmjkj/swagger-dubbo.git
