工程报错如下:
org.hibernate.LazyInitializationException: could not initialize proxy - no Session解决方法:
在类的头部加上@org.hibernate.annotations.Proxy(lazy = false)
@Entity @Table(name="csdnbbs_sys_catalog") @org.hibernate.annotations.Proxy(lazy = false) public class Catalog { private Catalog parent ; private String id ; private String name ; private String url ; private Set<Catalog> children = new HashSet<Catalog>(); @OneToMany(cascade=CascadeType.ALL, mappedBy="parent") public Set<Catalog> getChildren() { return children; } public void setChildren(Set<Catalog> children) { this.children = children; }
