您好，我有以下问题，当我加载没有@inject private Gson gson 的类时，它运行正常，但是当我把它放入它时会抛出异常。

调用 gson 的类。

package core.control;

import java.util.List;

import javax.inject.Inject;
import javax.inject.Named;

import com.google.gson.Gson;

import core.dao.SistemaDao;
import core.model.Sistema;

@Named
public class SistemaControl {

    private SistemaDao sistemaDao;

    @Inject
    private Gson gson;

    @Inject
    public SistemaControl(SistemaDao sistemaDao) {
        this.sistemaDao = sistemaDao;
    }

    public String getTodosOsSistemas() {
        List<Sistema> sistemas = sistemaDao.buscarTodos();
        String json = "oiii";
        return json;
    }

}

创作者：

package core.control;

import javax.enterprise.inject.Disposes;
import javax.enterprise.inject.Produces;

import com.google.gson.Gson;

public class CriadorGson {

    @Produces
    public Gson criarGson() {
        Gson gson = new Gson();
        return gson;
    }

    public void destruir(@Disposes Gson gson) {
        gson = null;
    }

}

调用调用 Gson 的 bean 的类

package core.jsfConnection;

import javax.enterprise.context.RequestScoped;
import javax.inject.Inject;
import javax.inject.Named;

import core.control.SistemaControl;

@Named("sistemaMB")
@RequestScoped
public class SistemaMB {

    @Inject
    private SistemaControl sistemaControl;

    public String getTodosSistemas() {
        String sistemasJson = sistemaControl.getTodosOsSistemas();
        return sistemasJson;
    }

}

例外

这不是 Gson 的问题。在您的 SistemaMB 类中提供 SistemaControl 的是什么？从堆栈跟踪看起来什么都没有。

例如，您可以向此类添加 Produces 方法：

public class CriadorModule {

    @Produces
    public SistemaControl criarSistemaControl() {
        return new SistemaControl();
    }

    @Produces
    public Gson criarGson() {
        Gson gson = new Gson();
        return gson;
    }

    // FYI the destroy in your CriadorGson class has no effect, you need to understand how variables work in Java. gson is a local copy of a reference.

}

似乎无法注入 sistemaControl。@javax.enterprise.inject.Default() 是您未指定时使用的默认限定符（在@Inject 旁边）。如果您使用 Java EE 6，请确保您已创建 beans.xml 以启用 CDI（默认情况下，托管 bean 是带注释的，例如使用 @Named）。如果您使用 Java EE 7，那么...应该启用 CDI；然后确保在 beans.xml 上，属性 bean-discovery-mode 未设置为“none”。

希望这可以帮助。
