错误 WELD-001303：范围类型 jakarta.enterprise.context.SessionScoped 没有活动上下文

如何解决错误 WELD-001303：范围类型 jakarta.enterprise.context.SessionScoped 没有活动上下文

在 tomcat9、Java8 -> 没问题。

我要升级到 tomcat 10、Java16

<dependency>
    <groupId>org.jboss.weld.se</groupId>
    <artifactId>weld-se-core</artifactId>
    <version>4.0.0.Final</version>
</dependency>
<dependency>
    <groupId>jakarta.enterprise</groupId>
    <artifactId>jakarta.enterprise.cdi-api</artifactId>
    <version>3.0.0</version>
</dependency>
<dependency>
    <groupId>jakarta.inject</groupId>
    <artifactId>jakarta.inject-api</artifactId>
    <version>2.0.0</version>
</dependency>

这是我的 beans.xml

<beans xmlns="https://jakarta.ee/xml/ns/jakartaee"
        xmlns:xsi="http://www.w3.org/2001/XMLSchema-instance"
        xsi:schemaLocation="https://jakarta.ee/xml/ns/jakartaee https://jakarta.ee/xml/ns/jakartaee/beans_3_0.xsd"
        version="3.0"
        bean-discovery-mode="all">
</beans>

Session.java:

import jakarta.enterprise.context.SessionScoped;
import jakarta.enterprise.inject.spi.CDI;
import jakarta.ws.rs.ForbiddenException;
import jakarta.ws.rs.core.SecurityContext;

/**
 * セッションインターフェース
 */
@SuppressWarnings("serial")
@SessionScoped
public class Session implements Principal,SecurityContext,Serializable,Map<String,Object> {

    /**
     * インスタンスを取得
     * 
     * @return インスタンス
     */
    public static Session current() {
        try {
            return CDI.current().select(Session.class).get();
        } catch (Exception e) {
            return new Session();
        }
    }

Main.java:

 @Inject private Session session;
 
 @GET @Path("index.html") public Object index() {
     if (session.getCategoryCode() != null) { 
         return Response.temporaryRedirect(URI.create("menu.html")).build();
     }
     return Tool.responseTemplate(template,"index",Notice.html(LocalDateTime.Now().format(Tool.yyyymmddhh))); }

当我在 If (session.getCategoryCode()... 会话变量总是显示“com.sun.jdi.InvocationException: 目标虚拟机调用方法发生异常。”

这是启动时的异常错误

当我在 org.jboss.weld.bean.proxy.ClientProxyProvider 调试时

public <T> T getClientProxy(final Bean<T> bean,Type requestedType) {
    // let's first try to use the proxy that implements all the bean types
    T proxy = beanTypeClosureProxyPool.getCastValue(bean);
    if (proxy == BEAN_NOT_PROXYABLE_MARKER) {
        /*
         *  the bean may have a type that is not proxyable - this is not a problem as long as the unproxyable
         *  type is not in the type closure of the requested type
         *  https://issues.jboss.org/browse/WELD-1052
         */
        proxy = requestedTypeClosureProxyPool.getCastValue(new RequestedTypeHolder(requestedType,bean));
        if (proxy == BEAN_NOT_PROXYABLE_MARKER) {
            throw Proxies.getUnproxyableTypeException(requestedType,services());
        }
    }
    BeanLogger.LOG.lookedUpClientProxy(proxy.getClass(),bean);
    return proxy;
}

requestedType 是 app.inject.Session（我的 SessionScoped 类） 在 T proxy = beanTypeClosureProxyPool.getCastValue(bean); 处始终显示“com.sun.jdi.InvocationException：目标 VM 中发生异常，发生调用方法。”

接下来，我创建 Test.java 并仅在 Main.java 中注入它

@SessionScoped
public class Test implements Serializable{
    private static final long serialVersionUID = 1L;
    private String id;
    public String getId() {
        return id;
    }
    public void setId(String id) {
        this.id = id;
    }
}

Main.java

    @Inject
    private Test test;
    
    @GET
    @Path("index.html")
    public Object index() {
        if (session.getCategoryCode() != null) { 
            return Response.temporaryRedirect(URI.create("menu.html")).build();
        }
        return Tool.responseTemplate(template,Notice.html(LocalDateTime.Now().format(Tool.yyyymmddhh)));
    }

所以它显示了同样的错误。

ApplicationScoped,RequestScoped,Dependent...=> 没问题。 只有 SessionScoped 错误。

如何解决？

解决方法

问题：jersey-cdi2-se 在 servlet 环境中不起作用。

改为jersey-cdi1x-servlet => DONE!!!!!!!!!!!!!!!
