filterObject是使用@PreFilter和@PostFilter时的一个内置表达式,表示集合中的当前对象。当@PreFilter标注的方法拥有多个集合类型的参数时,需要通过@PreFilter的filterTarget属性指定当前@PreFilter是针对哪个参数进行过滤的。 如下面代码就通过filterTarget指定了当前@PreFilter是用来过滤参数ids的。 @PreFilter(filterTarget=...
使用@PreFilter和@PostFilter时,Spring Security将移除使对应表达式的结果为false的元素。 @PostFilter("filterObject.id%2==0")publicList<User>findAll(){List<User>userList=newArrayList<User>();Useruser;for(inti=0;i<10;i++){user=newUser();user.setId(i);userList.add(user);}returnuserList;} ...
Spring Security中定义了四个支持使用表达式的注解,分别是@PreAuthorize、@PostAuthorize、@PreFilter和@PostFilter。其中前两者可以用来在方法调用前或者调用后进行权限检查,后两者可以用来对集合类型的参数或者返回值进行过滤。要使它们的定义能够对我们的方法的调用产生影响我们需要设置global-method-security元素的pre-post...

Under normal conditions, the post filter discharges almost no liquid water. If so, the air-water separator or drain valve inside the dryer is faulty. 3. The pre-filter can initially filter and purify the compressed air, and can filter out a large amount of water, oil and larger particles...
FIR prefilters and postfilters that jointly minimize a frequency-weighted mean-square error between the original and reconstructed signals can be designed. There is no need for ideal filter prototypes: the optimal pre-postfilter pair is determined from the signal and noise spectra and the up-...
