我是Java EE新手。我想测试JSF，因此制作了一个简单的程序，但无法部署它。我收到以下错误消息：
cannot Deploy onlineshop-war deploy is failing=Error occurred during deployment: Exception while loading the app : CDI deployment failure:WELD-001408: Unsatisfied dependencies for type Customer with qualifiers @Default at injection point [BackedAnnotatedField] @Inject private de.java2enterprise.onlineshop.RegisterController.customer at de.java2enterprise.onlineshop.RegisterController.customer(RegisterController.java:0) . Please see server.log for more details.
我的代码如下：
Customer.java：
package de.java2enterprise.onlineshop.model;
public class Customer {
private String email;
private String password;
}
registerController.java：
package de.java2enterprise.onlineshop;
import java.io.Serializable;
import javax.enterprise.context.RequestScoped;
import javax.inject.Named;
import javax.inject.Inject;
import de.java2enterprise.onlineshop.model.*;
@Named
@RequestScoped
public class RegisterController {
private static final long serialVersionUID = 1L;
@Inject
private Customer customer;
public Customer getCustomer() {
return customer;
}
public void setCustomer(Customer customer) {
this.customer = customer;
}
public String persist() {
return "/index.xhtml";
}
}
为了编译它，我必须包含cdi-api.jar作为外部库。谁在这里谁可以帮助我？谢谢大家。
您的Customer类必须由CDI作为bean发现。为此你有两个选择：
>把bean defining annotation放在上面。因为@Model是一个刻板印象，所以它就是这样做的原因。像@Named这样的限定符不是定义注释的bean，因为它不起作用
>通过在jar中添加beans.xml文件，将bean discovery mode in your bean archive从默认的“annotated”更改为“all”。
