简单的权限管理-资源，角色，用户，部门（一）

在ssh框架下，分为资源：menu，角色：role，用户user，其中menu和role是多对多关系，role和user是多对多关系，分为三个层级管理。

menu是控制url访问地址的，是属于粗粒度的权限控制

1.menu

public class Menu implements Serializable {
private static final long serialVersionUID = 1L;
private Long id;
private String lable;//标签
private String uri;
private String description;
private Integer status;
private Date date;

private Set<Role> roles=new HashSet<Role>();

public String getStatusStr(){
if(status==1){
return "启用";
}else{
return "禁用";
}
}
public String getOperStr(){
if(status==0){
return "启用";
}else{
return "禁用";
}
}
public Long getId() {
return id;
}
public void setId(Long id) {
this.id = id;
}
public String getLable() {
return lable;
}
public void setLable(String lable) {
this.lable = lable;
}
public String getUri() {
return uri;
}
public void setUri(String uri) {
this.uri = uri;
}
public String getDescription() {
return description;
}
public void setDescription(String description) {

}
public Set<Role> getRoles() {

public void setRoles(Set<Role> roles) {

}
public Integer getStatus() {
return status;
}
public void setStatus(Integer status) {
this.status = status;
}

}
