spring-webmvc-4.1.6 接口返回json数据中文出现u0000问题(2)_H5之家

<beans>
    <bean id="MovieLister" class="spring.MovieLister">
        <property name="finder">
            <ref local="MovieFinder"/>
        </property>
    </bean>
</beans>
3 接口：

public interface InjectFinder {
void injectFinder(MovieFinder finder);
}

class MovieLister implements InjectFinder

public void injectFinder(MovieFinder finder) {
this.finder = finder;
}

服务定位器

依赖注入最主要的好处是移除了MovieLister和MovieFinder的implementation（实现）上的依赖。但这并不是唯一的方法，另一种方法是服务定位器。

class ServiceLocator...

private static ServiceLocator soleInstance;
public static void load(ServiceLocator arg) {
      soleInstance = arg;
}
private Map services = new HashMap();
public static Object getService(String key){
      return soleInstance.services.get(key);
}
public void loadService (String key, Object service) {
      services.put(key, service);
}

class Tester...

private void configure() {
      ServiceLocator locator = new ServiceLocator();
      locator.loadService("MovieFinder", new ColonMovieFinder("movies1.txt"));
      ServiceLocator.load(locator);
}

class MovieLister...

MovieFinder finder = (MovieFinder) ServiceLocator.getService("MovieFinder");
依赖注入对于服务定位器来说是一种备选方案。服务定位器因为它的直接行为而有些许优势，但是如果你在很多应用中创建classes的时候，依赖注入是一种更好的选择。

思考：

1.Service Locator vs Dependency Injection

2.Constructor versus Setter Injection

3.Code or configuration files

4.Separating Configuration from Use

HashMap<String, Object> map= new HashMap<String, Object>();
  //顶级菜单
  List<DedeArctypes> toplist=testService.findDedeArctypes(topid,reid,typeid,"topid");
  //二级菜单
     for (DedeArctypes dedeArctypes1 : toplist) {
     System.out.println("一级菜单"+dedeArctypes1.getTypename());
     List<DedeArctypes> reidlist1=testService.findDedeArctypes(topid,dedeArctypes1.getId(),typeid,"reid");

     map.put(dedeArctypes1.getId()+"", reidlist1);
         for (DedeArctypes dedeArctypes2 : reidlist1) {
         System.out.println("二级菜单"+dedeArctypes2.getTypename());
         List<DedeArctypes> reidlist2=testService.findDedeArctypes(topid,dedeArctypes2.getId(),typeid,"reid");
      map.put(dedeArctypes2.getId()+"", reidlist2);
      for (DedeArctypes dedeArctypes3 : reidlist2) {
        System.out.println("三级菜单"+dedeArctypes3.getTypename());
    }
   }
     }
