java - 如何纠正 "The injection target must not be declared static."警告

Question

我收到警告

“IssuePermitProcessManager.ecmManagerLocal 注入(inject)目标不得声明为静态。”

在我的 WebSphere 9 服务器控制台上。我相信导致问题的代码是:

@Stateless
@TransactionManagement(TransactionManagementType.BEAN)
public class IssuePermitProcessManager implements IssuePermitProcessManagerRemote, IssuePermitProcessManagerLocal {

    @Resource
    private UserTransaction userTransaction;

    @EJB
    protected static EcmManagerLocal ecmManagerLocal = null;
    protected final static String EcmManagerLocal_JNDI = "ejblocal:gov.mo.dnr.ecwis.sessions.ecm.EcmManagerLocal";

我不清楚注入(inject)目标是什么。我是否只需从 protected static EcmManagerLocal ecmManagerLocal = null; 声明中删除 static 即可？

Answer 1

是的，ecmManagerLocal 是一个声明为静态的注入(inject)目标(它用 @EJB 注释来注入(inject) ejb)。替换该行代码，

    @EJB
    protected static EcmManagerLocal ecmManagerLocal = null;

与

    @EJB
    protected EcmManagerLocal ecmManagerLocal;
