Question

myeclipse9 支持jdk1.8吗

myeclipse9 应用tomcat7 + jdk 1.8。

org.springframework.beans.factory.BeanCreationException: Error creating bean with name 'vehicleInfoEnterService' defined in ServletContext resource [/WEB-INF/spring/service-vehicle.xml]: Instantiation of bean failed; nested exception is org.springframework.beans.BeanInstantiationException: Could not instantiate bean class [com.canco.vehicle.service.impl.VehicleInfoEnterSreviceImpl]: Constructor threw exception; nested exception is java.lang.Error: Unresolved compilation problems:
The type java.util.function.UnaryOperator cannot be resolved. It is indirectly referenced from required .class files
The type java.util.function.Predicate cannot be resolved. It is indirectly referenced from required .class files
The type java.util.function.Consumer cannot be resolved. It is indirectly referenced from required .class files

Answer 1

支持的，不过版本有点高。建议用1.7或者1.6版本
在window -preference --myeclipse----server ---tomcat下配置tomcat；
在window -preference --java---JRE下配置jdk即可。

Answer 2

这个的是可以的 啊

我就用的myeclipse9 + tomcat7 + jdk 1.8。
但是报错。启动项目工程就报错。
The type java.util.function.UnaryOperator cannot be resolved. It is indirectly referenced from required .class files

追答

解决的办法是：右击工程目录下的jdk 选择 build path---->config build path 或者在eclipse菜单栏点击project----->propertys 在里面再选择Java Build Path -----> Libraries---->Add Libraries----->JRE System Library
这个的话是你的JDK太多了 采纳吧

我的项目之前使用jdk1.6版本的。现在用更改为jdk1.8版本的。我知道怎么更改jdk。

我更改完之后类中就会报莫名其妙的错误。

启动项目也报错：The type java.util.function.UnaryOperator cannot be resolved. It is indirectly referenced from required .class files
