Spring配置文件实例01（实例：-学生-书包-书籍-）建好一个测试java工程简单描述第一个简单案例：通过spring配置（属性注入，构造函数的注入）来生成多个学生。构造一个studentbean（三个属性）privateStringstudentname;privateStringorigin;privateintage为其构造set(),get()方法。为其生成构造函数在spring的配置文件中对其进行属性注入或构造函数注入<!--学生的bean属性注入--><beanid="student1"class="com.workit.bean.StudentBean"><propertyname="studentname"value="jack"></property><propertyname="origin"value="eng"></property><propertyname="age"value="23"></property></bean><!--student2的构造函数--><beanid="student2"class="com.workit.bean.StudentBean"><constructor-argname="origin"type="String"value="usa"></constructor-arg><constructor-argname="age"type="int"value="23"></constructor-arg></bean>在配置文件生成好后，方可进行简单的测试编写简单的测试类：publicstaticvoidmain(String[]args){//TODOAuto-generatedmethodstubApplicationContextac=newClassPathXmlApplicationContext("applicationContext.xml");StudentBeanstudent1=(StudentBean)ac.getBean("student1");for(inti=0;i<student1.getPb().getListbook().size();i++){System.out.println(student1.getStudentname()+"\t"+student1.getOrigin()+"\t"+student1.getAge());}System.out.println("~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~");StudentBeanstudent2=(StudentBean)ac.getBean("student2");for(inti=0;i<student2.getPb().getListbook().size();i++){System.out.println(student2.getStudentname()+"\t"+student2.getOrigin()+"\t"+student2.getAge());}在生成学生后，完成相关扩充：在学生类添加属性书包，一个学生（多属性）可拥有多个书包，书包里面可装多本书籍…与上述方法雷同，重新编写studentbeanprivateStringstudentname;privateStringorigin;privateintage;privatePackgebookBeanpb;privatePropertiesproperties;构建书包类：PackgebookBeanprivateStringpackgename;privateintweight;List<BookBean>listbook;privateMap<String,String>pbmap;privateList<String>bookstr;privateList<BookBean>listotherbook;privateMap<String,BookBean>bookmap;privateSet<String>listbstr;privateSet<BookBean>setbookbean;构建书籍类：BookBeanprivateStringb
