java如何纠正“注入目标不能声明为静态的”警告

Question

我收到了警告

“IssuePermitProcessManager.ecmManagerLocal注入目标不能声明为静态。”

在我的WebSphere 9服务器控制台上。我认为导致问题的代码是：

@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";

我不清楚注射目标是什么。我只是从protected static EcmManagerLocal ecmManagerLocal = null;声明中删除static吗

Answer 1

是的，ecmManagerLocal是一个声明为静态的注入目标（用@EJB注释它以注入ejb）。替换代码行

    @EJB
    protected static EcmManagerLocal ecmManagerLocal = null;

与

    @EJB
    protected EcmManagerLocal ecmManagerLocal;
