今天完成的事情:

1.重新建立了项目

之前的总是找不到bean ，今天重新弄了一个项目

2.配置了两个service

这个可以随机访问

贴一下代码

int flag = Math.random()>0.5? 1:0;
System.out.println("产生随机数是："+flag);
List<Student> studentList = null;
String word=null;
try {
    switch (flag) {
        case 1:
            StudentService studentService = (StudentService) context.getBean("studentService");
            System.out.println("第一层访问service");
            studentList= studentService.getAllStudent();
            word = studentService.Login(student.getUser()).getPassword();
            break;
        default:
            StudentService studentService1 = (StudentService) context.getBean("studentService1");
            System.out.println("第二层访问service1");
            studentList = studentService1.getAllStudent();
            word = studentService1.Login(student.getUser()).getPassword();
            break;
    }
}catch (Exception e) {
    switch (flag) {
        case 1:
            StudentService studentService1 = (StudentService) context.getBean("studentService1");
            System.out.println("第一层访问失败，转到访问第二层service1");
            studentList= studentService1.getAllStudent();
            word = studentService1.Login(student.getUser()).getPassword();
            break;
        default:
            StudentService studentService = (StudentService) context.getBean("studentService");
            System.out.println("第一层访问失败，转到访问第二层service");
            studentList = studentService.getAllStudent();
            word = studentService.Login(student.getUser()).getPassword();
            break;
    }
}
