我一直试图让Guice工作但最终得到这个:

类必须具有一个(且只有一个)构造函数

我的界面:

public interface AddrBookStore {
    public Contact getContactByKey(String key);
    public void addContact(Contact c);
}

实施:

public class RdbmsBasedAddrBookStore implements AddrBookStore {
    private Connection connection;

    public RdbmsBasedAddrBookStore(Connection connection) {
        this.connection = connection;
    }

    @Override
    public Contact getContactByKey(String key) throws AddrBookException
    {} 
    @Override
    public void addContact(Contact c) throws AddrBookException
    {}
}

绑定模块:

public class ABguiceConfingModule extends AbstractModule {
    @Override
    protected void configure() {        
        bind(AddrBookStore.class).to(RdbmsBasedAddrBookStore.class);
    }
}

AddrBook我注射的客户:

public class AddrBook {
    private AddrBookStore store;

    @Inject
    public AddrBook(AddrBookStore store)
    { …
