Struts2接收参数的几种方式1.用Action的属性：在action里面定义要接收的参数，并提供相应的setter,getter,和提交参数的名称一致，并不用做数据类型的转换。相应提交方式可以用get和post，如：testAction?name=admin如：publicclassTestActionextendsBaseAction{privatestaticfinallongserialVersionUID=-7463970150000893325L;privateStringname;publicvoidexeceute(){System.out.println(name+":"+name);}publicStringgetName(){returnname;}publicvoidsetName(Stringname){this.name=name;}}2.使用DomainModel：在Action里面Model层用。相应不存很多的属性，而是用get和post，到的模型，保存它的一个对象提交方式可以用如：testAction?resBananRc.name=admin如：publicclassTestActionextendsBaseAction{privatestaticfinallongserialVersionUID=-7463970150000893325L;privateResBananRcresBananRc;publicResBananRcgetResBananRc(){returnresBananRc;}publicvoidsetResBananRc(ResBananRcresBananRc){this.resBananRc=resBananRc;}publicvoidexeceute(){System.out.println("姓名:"+resBananRc.getName());}}3.使用DTO--数据传输对象它的作用是接收参数，传递参数，并不是项目中的实体类。如用户注册时，会用到确认密码，所以要先把参数接收过来，做处理后，再传递给相应方法去创建User对象。提交参数的方式的DomailModel方式的相同。DTO：publicclassUserDTO{privateStringname;privateStringpassword;privateStringconfirm;publicStringgetName(){returnname;}publicvoidsetName(Stringname){this.name=name;}publicStringgetPassword(){returnpassword;}publicvoidsetPassword(Stringpassword){this.password=password;}publicStringgetConfirm(){returnconfirm;}publicvoidsetConfirm(Stringconfirm){this.confirm=confirm;}}Action：publicclassTestActionextendsBaseAction{privatestaticfinallongserialVersionUID=-7463970150000893325L;privateUserDTOuserDTO;publicUserDTOgetUserDTO(){returnuserDTO;}publicvoidsetUserDTO(UserDTOuserDTO){this.userDTO=userDTO;}publicvoidexeceute(){System.out.println("姓名:"+userDTO.getName());}}4.使用ModelDriven:在创建Action的时候，发现Action实现了ModelDriven接口，去调用接口的getModel()方法，取到了相关对象。相应提交方式可以用get和post，如：testAction?name=adminpublicclassTestActionextendsBaseActionimplementsModelDriven<ResBananRc>{privatestaticfinallongserialVersionUID=-7463970150000893325L;privateResBananRcresBananRc=newResBana
