spring3 MVC及spring security在方法中获取spring security用户名及角色以及提交form时字符串String与日期Date类型的绑定

1、在方法中获取spring security用户名及角色

private UserDetails getUserDetail(){
return (UserDetails) SecurityContextHolder.getContext()
.getAuthentication()
.getPrincipal(); www.zzzyk.com
}

private User getUser(){
String userName = getUserDetail().getUsername();
return service.findUserByLogName(userName);
}

private String getRoles(){
Collection<? extends GrantedAuthority> auths = getUserDetail().getAuthorities();
String result = "";
Object[] ats = auths.toArray();
for(int i=0; i<ats.length; i++){
   GrantedAuthority o = (GrantedAuthority)ats[i];
   result = result + o.getAuthority();
   if(i != ats.length - 1){
    result += ",";
   }
}
return result;
}

2、提交form时字符串String与日期Date类型的绑定

@InitBinder
//此处的参数也可以是ServletRequestDataBinder类型
public void initBinder(WebDataBinder binder) throws Exception {
     //注册自定义的属性编辑器
     //1、日期
     DateFormat df = new SimpleDateFormat("yyyy-MM-dd HH:mm:ss");
     CustomDateEditor dateEditor = new CustomDateEditor(df, true);
     //表示如果命令对象有Date类型的属性，将使用该属性编辑器进行类型转换
     binder.registerCustomEditor(Date.class, dateEditor);
     //自定义的电话号码编辑器(和【4.16.1、数据类型转换】一样)
     //binder.registerCustomEditor(PhoneNumberModel.class, new PhoneNumberEditor());
}
