无法使用 @inject 在 java 中注入 Gson
Cant inject Gson in java with @inject
你好，我有以下问题，当我在没有@inject private Gson gson 的情况下加载 class 时，它运行正常，但是当我放置它时，它会抛出异常。
Class 调用 gson.
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gson的bean的class
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;
}
}
异常

问题不在于 Gson。什么在您的 SistemaMB class 中提供 SistemaControl？从堆栈跟踪来看，它看起来什么都没有。
例如，您可以将 Produces 方法添加到此 class:
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.
}
sistemaControl 似乎无法注入。 @javax.enterprise.inject.Default() 是默认使用的限定符，如果你没有指定任何（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 beans 是被注释的 beans，例如 @Named）。如果您使用 Java EE 7 那么...应该启用 CDI；然后确保比 beans.xml 属性 bean-discovery-mode 没有设置为 'none'。
希望对您有所帮助。
你好，我有以下问题，当我在没有@inject private Gson gson 的情况下加载 class 时，它运行正常，但是当我放置它时，它会抛出异常。
Class 调用 gson.

return json;

问题不在于 Gson。什么在您的 SistemaMB class 中提供 SistemaControl？从堆栈跟踪来看，它看起来什么都没有。
例如，您可以将 Produces 方法添加到此 class:
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.
}
sistemaControl 似乎无法注入。 @javax.enterprise.inject.Default() 是默认使用的限定符，如果你没有指定任何（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 beans 是被注释的 beans，例如 @Named）。如果您使用 Java EE 7 那么...应该启用 CDI；然后确保比 beans.xml 属性 bean-discovery-mode 没有设置为 'none'。
希望对您有所帮助。
