Use of the Web base-----> template engine Velocity (ii)

This is about some of the usage of velocity, the use of more basic.

Velocity Generation JavaBean

First, define a simple bean class

 Public classClassbean {PrivateString name; PrivateString Comment;  PublicString GetName () {returnname; }     Public voidsetName (String name) { This. Name =name; }     PublicString getcomment () {returncomment; }     Public voidsetcomment (String comment) { This. Comment =comment; }}

Ii. Velocity code for generating JavaBean

Privatevelocityengine init () {Velocityengine ve=NewVelocityengine (); Ve.setproperty (Runtimeconstants.resource_loader,"Classpath"); Ve.setproperty ("Classpath.resource.loader.class", Classpathresourceloader.class. GetName ());    Ve.init (); returnve;}
@Test Public voidvelocity_test_2 () {velocityengine ve=init (); Template T= Ve.gettemplate ("TEMPLATE/CLASSVELOCITY.VM"); Velocitycontext CTX=NewVelocitycontext (); //DataList<classbean> Classbeans =NewArraylist<>(); Classbean ClassBean1=NewClassbean (); Classbean1.setname ("Username"); Classbean1.setcomment ("User Name"); Classbean classBean2=NewClassbean (); Classbean2.setname ("Password"); Classbean2.setcomment (Password); Classbean classBean3=NewClassbean (); Classbean3.setname ("Address"); Classbean3.setcomment (Address);    Classbeans.add (CLASSBEAN1);    Classbeans.add (CLASSBEAN2);    Classbeans.add (CLASSBEAN3); Ctx.put ("ClassName", "person"); Ctx.put ("List", Classbeans); StringWriter SW=NewStringWriter ();    T.merge (CTX, SW); System.out.println (Sw.tostring ());}

Third, the contents of CLASSVELOCITY.VM are as follows

# #首字母大写 #macro (inituppercase $field) $field. toUpperCase (). substring (0,1) $field. Substring (1) # # #end Public class$className {#foreach($beaninch$list)PrivateString $bean. GetName ();//$bean. Getcomment ()#end #foreach($beaninch$list) #Set($filed =$bean. GetName ()) PublicStringGet#initUpperCase ($filed) () {return$filed; }     Public void Set#initUpperCase ($filed) (String $filed) { This. $filed =$filed; } #end}

Iv. the generated code is as follows:

 Public classPerson {PrivateString username;//User name    PrivateString password;//Password    PrivateString address;//Address     PublicString GetUserName () {returnusername; }     Public voidSetusername (String username) { This. Username =username; }     PublicString GetPassword () {returnpassword; }     Public voidSetPassword (String password) { This. Password =password; }     PublicString getaddress () {returnaddress; }     Public voidsetaddress (String address) { This. Address =address; }}
