我试图了解Weld CDI容器如何与JPMS一起工作。所以我有以下配置。
module my.module {
requires weld.se.shaded;
exports com.foo;
}
新建类
package com.foo;
import javax.enterprise.context.ApplicationScoped;
import javax.inject.Inject;
@ApplicationScoped
public class NewClass {
@Inject
private NewBean bean;
public void doIt() {
bean.doIt();
}
}
NewBean类
package com.foo;
import javax.enterprise.context.Dependent;
@Dependent
public class NewBean {
public void doIt() {
System.out.println("I am doing it");
}
}

如何解释此异常
将字段设为私有com。傅。NewBean公司。傅。新建类。可访问bean:
有一张桌子

从中我可以理解自动模块可以读取命名(应用)模块。那为什么没有呢?
