Recently in the OA system: roles (role) and permissions (Privilege) are many-to-many relationships, entity-class relationship mapping takes the form of annotationsMapping permission relationships in a role class@ManyToMany public set getprivileges () { return privileges ;}Mapping role relationships in permission classes@ManyToMany (mappedby= "Privileges") public set getroles () { return roles;}Part of the UPDATE function code: 1. Set permissions properties in roles; 2. Update to Data

Use ". +?" To implement the middle fuzzy matching code: public class Test { public static void main (string[] args) {Stri ng str = always drunk in a moment of retrospect, Wet a soft heart. There will always be a moment to review the time drunk, wet a soft heart =str.replaceall ( always in. +" Fleeting " Span style= "color: #800000;" > ", " There's always a time to be looking back on a hangover. " ); System. out .println (str); } } Note: Only fuzzy matching of

as "fixed code snippet")The meaning of fixture is "code that must be called at certain stages". For example, the above test, because only a calculator object is declared, his initial value is 0, but after testing the addition operation, his value is not 0, and then test the subtraction operation, it is necessary to consider the results of the last addition operation. This is definitely a very bad design! We very much hope that each test is independent and that there is no coupling between each

message queue identifiers. Message Queuing overcomes the disadvantages of less signal transmission information, only unformatted byte stream, and limited buffer size. Shared storage sharedmemory: Shared memory is the mapping of memory that can be accessed by other processes, which is created by a process, but can be accessed by multiple processes. Shared memory is the fastest IPC approach and is specifically designed for low-efficiency operation of other interprocess communication modes. It
