假设在Spring配置文件中有这样的配置信息<;bean id="foo" class="com.spring.Foo"/>;则要创建一个Spring Bean的正确用法是？
A: MyBean myBean = (MyBean)factory.getBean("foo");
B: MyBean myBean = (MyBean)factory.getBean("com.spring.Foo");
C: MyBean myBean = (MyBean)factory.newBean("foo");
D: MyBean myBean = (MyBean)factory.newBean("com.spring.Foo");
A: MyBean myBean = (MyBean)factory.getBean("foo");
B: MyBean myBean = (MyBean)factory.getBean("com.spring.Foo");
C: MyBean myBean = (MyBean)factory.newBean("foo");
D: MyBean myBean = (MyBean)factory.newBean("com.spring.Foo");
举一反三
- 【单选题】对于以下标签[br][/br]它与下列哪个选项中的Java程序片段等价 A: %CounterBean myBean=(CounterBean)request.getAttribute(“myBean”);if(myBean==null)myBean = new CounterBean();% B: %CounterBean myBean=(CounterBean)request.getAttribute(“myBean”);if(myBean==null){myBean = new CounterBean();request.setAttribute(“CounterBean”,myBean);}% C: %CounterBean myBean=(CounterBean)request.getAttribute(“myBean”);if(myBean==null){myBean = new CounterBean();request.setAttribute(“myBean”,myBean);}% D: %CounterBean myBean=new CounterBean();request.setAttribute(“myBean”,myBean);%
- 在JSP页面中，（）可以正确引入JavaBean。 A: <%jsp: useBean id =”myBean” scope =”page” class=”pkg.MyBean” %> B: <jsp: useBean name =”myBean” scope =”page” class=”pkg.MyBean” > C: <jsp: useBean id =”myBean” scope =”page” class=”pkg.MyBean” /> D: <jsp: useBean name =”myBean” scope =”page” class=”pkg.MyBean” />
- 在JSP页面中，正确引入JavaBean的是（） A: <%jsp: useBean id =”myBean” scope =”page” class=”pkg.MyBean” %> B: <jsp: useBean name=”myBean” scope =”page” class=”pkg.MyBean” > C: <jsp: useBean id =”myBean” scope =”page” class=”pkg.MyBean” /> D: <jsp: useBean name=”myBean” scope =”page” class=”pkg.MyBean” />
- 在JSP中想要使用JavaBean:mypackage.mybean,则以下写法正确的是() A: ”mybean”scope=”pageContext”class=”mypackage.mybean”/> B: <jsp:useBeanclass=”mypackage.mybean.class”/> C: ”mybean”class=”mypackage.mybean.java”> D: ”mybean”class=”mypackage.mybean”/>
- 给定TheBean类，假设还没有创建TheBean类的实例，以下哪些JSP动作语句能创建这个bean的一个新实例，并把它存储在请求作用域（） A: <jsp :useBean name=\"myBean\" type=\"com.example.TheBean\"/> \n B: <jsp :takeBean name=\"myBean\" type=\"com.example.TheBean\"/> \n C: <jsp :useBean id=\"myBean\" class=\"com.example.TheBean\" scope=\"request\"/> \n D: <jsp :takeBean id=\"myBean\" class=\"com.example.TheBean\" scope=\"request\"/>
