Spring-如何给静态变量注入值

@Autowired
private static StudentMapper studentMapper;

Spring 依赖注入是依赖set方法，静态变量不属于对象，只属于类。解决方法就是加上非静态的set方法，如下：

private static StudentMapper studentMapper;

public StudentMapper getStudentMapper() {
        return studentMapper;
}

@Autowired
public void setStudentMapper(StudentMapper studentMapper) {
        this.studentMapper = studentMapper;
}
