我正在使用 Wildfly 10 和 Java 8。我尝试绑定(bind)我的服务 like here但我仍然收到此错误。我能看到的唯一区别是 pom.xml 依赖项,但 2.0-rc1 版本很旧。
[io.undertow.request] (default task-2) UT005023: Exception handling request to /api/account: javax.servlet.ServletException: A MultiException has 3 exceptions. They are:
1. org.glassfish.hk2.api.UnsatisfiedDependencyException: There was no object available for injection at SystemInjecteeImpl(requiredType=ICuentaService,parent=CuentaServiceRS,qualifiers={},position=-1,optional=false,self=false,unqualified=null,287721117)
2. java.lang.IllegalArgumentException: While attempting to resolve the dependencies of ar.com.olx.api.rest.CuentaServiceRS errors were found
3. java.lang.IllegalStateException: Unable to perform operation: resolve on ar.com.olx.api.rest.CuentaServiceRS
我的 API REST 类
@Path("/account")
public class CuentaServiceRS {
@Inject
private ICuentaService cuentaService;
@GET
@Produces(MediaType.APPLICATION_JSON)
public Cuenta getCuenta() {
return cuentaService.getCuentas().get(0);
}
}
pom.xml

<param-value>ar.com.villat.bind.ApplicationJaxRS</param-value>
</init-param>
<load-on-startup>1</load-on-startup>
</servlet>
我的应用程序 JAX-RS 类
public class ApplicationJaxRS extends ResourceConfig {
public ApplicationJaxRS(){
register(new CustomBinder());
packages(true, "ar.com.villat");
}
}
最后,我的自定义 Binder
public class CustomBinder extends AbstractBinder {
@Override
protected void configure() {
bind(ICuentaService.class).to(CuentaServiceImpl.class);
}
}
如果您需要更多详细信息,请告诉我
最佳答案
在AbstractBinder
中,它应该是bind(Implementation).to(Contract)
。你反之亦然。他们这样做的原因是一个实现可能有多个合约,因此您可以仅链接 to
调用。
