annotations

问题 I was wondering if my idea is possible with hibernate. What I want is that there is one table with usernames and every table wich has a reference to this table has the username encrypted in a column. So the username doesn't stand in normal text but encrypted in every table which have a reference to the user table. So I need something like: @ManyToOne @JoinColumn(name = "userName", insertable=false, updatable=false, encrypted="md5") public User getUser(){ return this.user; } public void

问题 So I made a function, and wanted to add annotations to it, and the compiler keeps giving me an error: def square_root(x:number, eps:number) -> float: pass And the compiler returns this: File "/Users/albertcalzaretto/Google Drive/CSC148H1/e1/e1a.py", line 1 def square_root(x, eps) -> float: ^ SyntaxError: invalid syntax I've never used function annotations, and I've read several sources about it, and I don't think what I'm doing is wrong. 回答1: Two things: You must be using Python 2.x somehow.

问题 Could you provide any example for routing messages in Spring Integration?. Filter by payload message, header or something like the following: <int:payload-type-router input-channel="routingChannel"> <int:mapping type="java.lang.String" channel="channel1" /> <int:mapping type="java.lang.Integer" channel="channel2" /> </int:payload-type-router> How the response works? I mean, if I send: channel -> router -> transformer -> gateway Simple but I am looking something similar to this example: <int

问题 I want to use two Modelica libraries together, in Dymola, so for convenience I wrote a little script, loadLibraries.mos that just opens the two libraries. But they use different versions of the MSL (3.2.1 versus 3.2.2), defined by the uses annotation in the top level package.mo: annotation(uses(Modelica(version="3.2.1"))); The library developed by us uses 3.2.2, the library that uses MSL 3.2.1 is developed by someone else. Now whenever I run the mos script (or when I open the two libraries

问题 Background Logging a project using aspects such that all methods, classes, and constructors that are marked with the @Log annotation have information written to a log file. Problem Methods appear to be called recursively one-level deep, but the code does not show any such recursive relationship.

问题 I think the title is quite self explanatory. Currently when I add a default annotation for current location: let currentAnnot = MKPointAnnotation() currentAnnot.coordinate = loc.coordinate mainMap.addAnnotation(currentAnnot) It is giving me a red pin. I want the same blue dot with light blue field which the Apple iPhone Maps app is using by default. Is there a special name for that and how can I add it? 回答1: It's because you're adding an annotation (pin) rather than the user location. Enable

问题 Is there any way to create a view when creating tables by using the hibernate.hbm2ddl.auto property. I am using annotation type for defining the table and its fields. Is there any property that I can use to create the view also through hibernate? 回答1: Hibernate does not do that for you automatically. However, one of these solutions might be useful to you: Create a view in your database, and define a model with those columns using hibernate. Hibernate does not create a table for that model, if

问题 I'm studying Spring 3 and I'm using it in a simple web-application. Now I'm implementing a Spring MVC Controller using annotations, and I'm wondering: Is there any best practice using @RequestMapping annotation? I mean: I've seen that usually the URL mapped in this annotation is hardcoded in the class... Is there a way to pass the URL in a 'loosely coupled way' (to obtain a more reusable class)? I know that there are some wild cards that can be used, but I think that isn't the solution... Am
