我要评论1、get请求
1.1 方法形参接收参数 这种方式一般适用参数比较少的情况，并且前后端参数名称必须保持一致
@restcontroller
@requestmapping("/user")
@slf4j
public class democontroller {
@getmapping("/query")
public void getstudent(string name,string age) {
log.info("name:{}",name);
log.info("age:{}",age);
}
}参数用 @requestparam 标注，使用value属性指定参数名，required属性表示这个参数是否必传
@restcontroller
@requestmapping("/user")
@slf4j
public class democontroller {
@getmapping("/query")
public void getstudent(@requestparam(value = "name", required = false) string name,
@requestparam(value = "age", required = false) string age) {
log.info("name:{}",name);
log.info("age:{}",age);
}
}1.2 实体类接收参数
注意：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。
@restcontroller
@requestmapping("/demo")
@slf4j
public class democontroller {
@getmapping("/query")
public void getstudent(student student) {
log.info("name:{}",student.getname());
log.info("age:{}",student.getage());
}
}
@data
class student{
private string name;
private integer age;
}1.3 通过httpservletrequest接收参数
@restcontroller
@requestmapping("/demo")
@slf4j
public class democontroller {
@getmapping("/query")
public void getstudent(httpservletrequest request) {
string name = request.getparameter("name");
string phone = request.getparameter("age");
log.info("name:{}",name);
log.info("age:{}",age);
}
}1.4 通过@pathvariable接收参数
@restcontroller
@requestmapping("/demo")
@slf4j
public class democontroller {
@getmapping("/query/{name}/{age}")
public void getstudent(@pathvariable string name, @pathvariable string age) {
log.info("name:{}",name);
log.info("age:{}",age);
}
}1.5 接收数组参数
@restcontroller
@requestmapping("/demo")
@slf4j
public class democontroller {
@getmapping("/query")
public void getstudent(string[] names) {
arrays.stream(names).foreach(system.out::println);
}
}1.6 接受集合参数
注意：springboot 接收集合参数，必须用 @requestparam 注解声明！
@restcontroller
@requestmapping("/demo")
@slf4j
public class democontroller {
@getmapping("/query")
public void getstudent(@requestparam list<string> names) {
names.foreach(system.out::println);
}
}2、post请求
2.1 方法形参接收参数 前后端参数名称必须保持一致
@restcontroller
@requestmapping("/user")
@slf4j
public class democontroller {
@postmapping("/save")
public void savestudent(string name,string age) {
log.info("name:{}",name);
log.info("age:{}",age);
}
}参数用 @requestparam 标注，使用value属性指定参数名，required属性表示这个参数是否必传
@restcontroller
@requestmapping("/user")
@slf4j
public class democontroller {
@postmapping("/save")
public void savestudent(@requestparam(value = "name", required = false) string name,
@requestparam(value = "age", required = false) string age) {
log.info("name:{}",name);
log.info("age:{}",age);
}
}2.2 通过httpservletrequest接收参数
@restcontroller
@requestmapping("/demo")
@slf4j
public class democontroller {
@postmapping("/save")
public void savestudent(httpservletrequest request) {
string name = request.getparameter("name");
string phone = request.getparameter("age");
log.info("name:{}",name);
log.info("age:{}",age);
}
}2.3 通过@pathvariable接收参数
@restcontroller
@requestmapping("/demo")
@slf4j
public class democontroller {
@postmapping("/save/{name}/{age}")
public void savestudent(@pathvariable string name, @pathvariable string age) {
log.info("name:{}",name);
log.info("age:{}",age);
}
}2.4 通过param方式提交参数，以实体类接收参数
直接以实体类可以接收param、form-data、 x-www-form-urlencoded 提交的参数
@restcontroller
@requestmapping("/demo")
@slf4j
public class democontroller {
@postmapping("/save")
public void savestudent(student student) {
log.info("name:{}",student.getname());
log.info("age:{}",student.getage());
}
}
@data
class student{
private string name;
private integer age;
}2.5 请求体以json格式提交参数，通过 @requestbody 注解接收参数
接受实体类json参数
@restcontroller
@requestmapping("/demo")
@slf4j
public class democontroller {
@postmapping("/save")
public void savestudent(@requestbody student student) {
log.info("name:{}",student.getname());
log.info("age:{}",student.getage());
}
}
@data
class student{
private string name;
private integer age;
}接收数组或者集合类json参数
@restcontroller
@requestmapping("/demo")
@slf4j
public class democontroller {
@postmapping("/save")
public void savestudent(@requestbody string[] names) {
arrays.stream(names).foreach(system.out::println);
}
@postmapping("/save")
public void savestudent(@requestbody list<string> names) {
names.foreach(system.out::println);
}
}2.6 通过 map 接收参数
@restcontroller
@requestmapping("/demo")
@slf4j
public class democontroller {
@postmapping("/save")
public void savestudent(@requestparam map<string,object> map) {
log.info("name:{}",map.get("name"));
log.info("age:{}",map.get("age"));
}
}2.7 通过@requestbody 接收一个参数
@restcontroller
@requestmapping("/demo")
@slf4j
public class democontroller {
@postmapping("/save")
public void savestudent(@requestbody string name) {
log.info("name:{}",name);
}
