這幾天研究WebService，測試啓什麼server很煩，直接寫main又嫌寫煩，乾脆寫了個簡單的發佈工具，通過load properties來實現publish。
上代碼：
public class Publisher {
public static void main(String[] args) throws IOException, ClassNotFoundException, InstantiationException, IllegalAccessException {
Properties pros = new Properties();
pros.load(Publisher.class.getResourceAsStream("service.properties"));
Set<String> keys = pros.stringPropertyNames();
if(keys != null){
Map<String, ServiceProperty> services = new HashMap<String, Publisher.ServiceProperty>();
for (String key : keys) {
String[] ks = key.split("\\.");
if(ks != null && ks.length==3 && "service".equalsIgnoreCase(ks[0])){
String name = ks[1];
ServiceProperty sp;
if(services.containsKey(name)){
sp = services.get(name);
}else{
sp = new ServiceProperty();
sp.name = name;
services.put(name, sp);
}
if("interface".equalsIgnoreCase(ks[2])){
sp.interfaceClass = pros.getProperty(key);
}else if("implements".equalsIgnoreCase(ks[2])){
sp.implementsClass = pros.getProperty(key);
}else if("address".equalsIgnoreCase(ks[2])){
sp.address = pros.getProperty(key);
}
}
}
outter : for (ServiceProperty sp : services.values()) {
Class<?> intClass = Class.forName(sp.interfaceClass);
Class<?> impClass = Class.forName(sp.implementsClass);
if(!intClass.isInterface()){
throw new RuntimeException("Service which named : " + sp.name + " the interface setting is error.");
}
for (Class<?> clazz : impClass.getInterfaces()) {
if(clazz.equals(intClass)){
String address = sp.address;
Object imp = impClass.newInstance();
System.out.println("Publish service : " + sp.name);
System.out.println("Service class : " + sp.implementsClass);
System.out.println("Service address : " + sp.address);
Object it = intClass.cast(imp);
Endpoint.publish(address, it);
continue outter;
}
}
}
}
}
static class ServiceProperty{
private String name;
private String interfaceClass;
private String implementsClass;
private String address;
}
}
要發佈也很簡單，在同目錄下的service.properties中配置就行：
service.userService.interface=com.wuningsi.ms.ws.UserService
service.userService.implements=com.wuningsi.ms.ws.UserServiceImpl
service.userService.address=http://ws.ms.wuningsi.com/user
很簡單的東西，就當玩玩了。
