1. Get 请求
1.1 以方法的形参接收参数
1.这种方式一般适用参数比较少的情况
java
复制代码
@RestController
@RequestMapping("/user")
@Slf4j
public class UserController {
@GetMapping("/detail")
public Result<User> getUserDetail(String name,String phone) {
log.info("name:{}",name);
log.info("phone:{}",phone);
return Result.success(null);
}
}
2.参数用 @RequestParam 标注，表示这个参数需要必传，否则会报错。
java
复制代码
@RestController
@RequestMapping("/user")
@Slf4j
public class UserController {
@GetMapping("/detail")
public Result<User> getUserDetail(@RequestParam String name,@RequestParam String phone) {
log.info("name:{}",name);
log.info("phone:{}",phone);
return Result.success(null);
}
}
1.2 以实体类接收参数
java
复制代码
@RestController
@RequestMapping("/user")
@Slf4j
public class UserController {
@GetMapping("/detail")
public Result<User> getUserDetail(User user) {
log.info("name:{}",user.getName());
log.info("phone:{}",user.getPhone());
return Result.success(null);
}
}
注：Get 请求以实体类接收参数时，不能用 RequestParam 注解进行标注，因为不支持这样的方式获取参数。
1.3 通过 HttpServletRequest 接收参数
java
复制代码
@RestController
@RequestMapping("/user")
@Slf4j
public class UserController {
@GetMapping("/detail")
public Result<User> getUserDetail(HttpServletRequest request) {
String name = request.getParameter("name");
String phone = request.getParameter("phone");
log.info("name:{}",name);
log.info("phone:{}",phone);
return Result.success(null);
}
}
1.4 通过 @PathVariable 注解接收参数
java
复制代码
@RestController
@RequestMapping("/user")
@Slf4j
public class UserController {
@GetMapping("/detail/{name}/{phone}")
public Result<User> getUserDetail(@PathVariable String name,@PathVariable String phone) {
log.info("name:{}",name);
log.info("phone:{}",phone);
return Result.success(null);
}
}
1.5 接收数组参数
java
复制代码
@RestController
@RequestMapping("/user")
@Slf4j
public class UserController {
@GetMapping("/detail")
public Result<User> getUserDetail(String[] names) {
Arrays.asList(names).forEach(name->{
System.out.println(name);
});
return Result.success(null);
}
}
1.6 接收集合参数
springboot 接收集合参数，需要用 RequestParam 注解绑定参数，否则会报错！！
java
复制代码
@RestController
@RequestMapping("/user")
@Slf4j
public class UserController {
@GetMapping("/detail")
public Result<User> getUserDetail(@RequestParam List<String> names) {
names.forEach(name->{
System.out.println(name);
});
return Result.success(null);
}
}
