#author("2019-11-18T14:58:06+08:00","default:Admin","Admin") SpringMVC 方法级别 †访问http://localhost/xxxx/departments的时候，会调用 simplePattern方法了 @RequestMapping(value="/departments")
public String simplePattern(){
System.out.println("simplePattern method was called");
return "someResult";
}
参数绑定 †形如这样的访问形式：就可以触发访问findDepatment方法了 /departments?departmentId=23 @RequestMapping(value="/departments")
public String findDepatment(
@RequestParam("departmentId") String departmentId){
System.out.println("Find department with ID: " + departmentId);
return "someResult";
}
REST风格的参数 †第一种 †形如REST风格的地址访问，比如：其中用(@PathVariable接收rest风格的参数 /departments/23 @RequestMapping(value="/departments/{departmentId}")
public String findDepatment(@PathVariable String departmentId){
System.out.println("Find department with ID: " + departmentId);
return "someResult";
}
第二种 †这个有点不同，就是接收形如/departments/23的URL访问，把23作为传入的departmetnId,， 但是在实际的方法findDepatmentAlternative中，使用@PathVariable("departmentId") String someDepartmentId，将其绑定为someDepartmentId,所以这里someDepartmentId为23 @RequestMapping(value="/departments/{departmentId}")
public String findDepatmentAlternative(@PathVariable("departmentId") String someDepartmentId){
System.out.println("Find department with ID: " + someDepartmentId);
return "someResult";
}
url中同时绑定多个id †@RequestMapping(value="/departments/{departmentId}/employees/{employeeId}")
public String findEmployee(
@PathVariable String departmentId,
@PathVariable String employeeId){
System.out.println("Find employee with ID: " + employeeId +
" from department: " + departmentId);
return "someResult";
}
正则表达式 †@RequestMapping(value="/{textualPart:[a-z-]+}.{numericPart:[\\d]+}")
public String regularExpression(
@PathVariable String textualPart,
@PathVariable String numericPart){
System.out.println("Textual part: " + textualPart +
", numeric part: " + numericPart);
return "someResult";
}
比如如下的URL： /sometext.123 则输出： Textual part: sometext, numeric part: 123. iディレクトリで複数のポータルサイトにディレクトリ登録
