先创建用户 之后通过刚刚创建的用户登录
创建工作空间 创建完成后他会自动进入到springbootweb工作空间
点击添加新请求 请求 pom.xml文件如下
?xml version1.0 encodingUTF-8?
project xmlnshttp://maven.apache.org/POM/4.0.0 xmlns:xsihttp://www.w3.org/2001/XMLSchema-instancexsi:schemaLocationhttp://maven.apache.org/POM/4.0.0 https://maven.apache.org/xsd/maven-4.0.0.xsdmodelVersion4.0.0/modelVersionparentgroupIdorg.springframework.boot/groupIdartifactIdspring-boot-starter-parent/artifactIdversion2.7.4/versionrelativePath/ !-- lookup parent from repository --/parentgroupIdcom.he1220/groupIdartifactIddemo/artifactIdversion0.0.1-SNAPSHOT/versionnamedemo/namedescriptionDemo project for Spring Boot/descriptionpropertiesjava.version11/java.version/propertiesdependenciesdependencygroupIdorg.springframework.boot/groupIdartifactIdspring-boot-starter-web/artifactId/dependencydependencygroupIdorg.springframework.boot/groupIdartifactIdspring-boot-starter-test/artifactIdscopetest/scope/dependency/dependenciesbuildpluginsplugingroupIdorg.springframework.boot/groupIdartifactIdspring-boot-maven-plugin/artifactId/plugin/plugins/build/project简单参数
以原始的方式接收请求参数 目录结构如下 RequestController.java文件内容如下
package com.he1220.demo.controller;import org.springframework.web.bind.annotation.RequestMapping;
import org.springframework.web.bind.annotation.RestController;import javax.servlet.http.HttpServletRequest;RestController
public class RequestController {RequestMapping(/simpleParam)public String simpleParam(HttpServletRequest request){String name request.getParameter(name);String age request.getParameter(age);System.out.println(name);System.out.println(age);return ok;}
}测试结果如下 以SpringBoot的方式接收请求参数
package com.he1220.demo.controller;import org.springframework.web.bind.annotation.RequestMapping;
import org.springframework.web.bind.annotation.RestController;RestController
public class RequestController {RequestMapping(/simpleParam)public String simpleParam(String name,Integer age){System.out.println(name);System.out.println(age);return ok;}
}如果方法形参名称与请求参数名称不匹配可以通过RequestParam注解完成映射 通过name属性指定请求参数名 RequestParam中的Required属性默认为true该请求参数必须传递不传递将报错(400)。可以设置为false package com.he1220.demo.controller;import org.springframework.web.bind.annotation.RequestMapping;
import org.springframework.web.bind.annotation.RequestParam;
import org.springframework.web.bind.annotation.RestController;RestController
public class RequestController {RequestMapping(/simpleParam)public String simpleParam(RequestParam(namename)String username,Integer age){System.out.println(username);System.out.println(age);return ok;}
}实体参数 需要保证请求参数名与形参对象属性名一致 目录结构如下 RequestController.java内容如下
package com.he1220.demo.controller;import com.he1220.demo.pojo.User;
import org.springframework.web.bind.annotation.RequestMapping;
import org.springframework.web.bind.annotation.RestController;RestController
public class RequestController {RequestMapping(/Pojo)public String Pojo(User user){System.out.println(user);return ok~;}
}User.java内容如下
package com.he1220.demo.pojo;public class User{private String name;private String age;private Add add;public User(String name, String age) {this.name name;this.age age;}public Add getAdd() {return add;}public String getName() {return name;}public String getAge() {return age;}public void setAge(String age) {this.age age;}public void setName(String name) {this.name name;}public void setAdd(Add add) {this.add add;}Overridepublic String toString() {return User{ name name \ , age age \ , add add };}
}Add.java内容如下
package com.he1220.demo.pojo;public class Add {private String province;private String city;public String getProvince() {return province;}public void setProvince(String province) {this.province province;}public String getCity() {return city;}public void setCity(String city) {this.city city;}Overridepublic String toString() {return Add{ province province \ , city city \ };}
}
测试结果如下 数组参数 RequestController.java内容如下
package com.he1220.demo.controller;import org.springframework.web.bind.annotation.RequestMapping;
import org.springframework.web.bind.annotation.RestController;
import java.util.Arrays;RestController
public class RequestController {RequestMapping(/arrParam)public String arrParam(String[] hobby){System.out.println(Arrays.toString(hobby));return ok~;}
}测试结果如下 集合参数 需要保证请求的参数名与集合变量名相同通过RequestParam注解绑定参数关系 RequestController.java内容如下
package com.he1220.demo.controller;import org.springframework.web.bind.annotation.RequestMapping;
import org.springframework.web.bind.annotation.RequestParam;
import org.springframework.web.bind.annotation.RestController;
import java.util.List;RestController
public class RequestController {RequestMapping(/listParam)public String listParam(RequestParam ListString hobby){System.out.println(hobby);return ok~;}
}日期参数 使用DateTimeFormat 注解完成日期参数格式转换 package com.he1220.demo.controller;import org.springframework.format.annotation.DateTimeFormat;
import org.springframework.web.bind.annotation.RequestMapping;
import org.springframework.web.bind.annotation.RestController;import java.time.LocalDateTime;RestController
public class RequestController {RequestMapping(/dateParam)public String dateParam(DateTimeFormat(pattern yyyy-MM-dd HH:mm:ss) LocalDateTime updateTime){System.out.println(updateTime);return ok~;} Json参数 通过RequestBody注解将Json对象封装到实体类当中 package com.he1220.demo.controller;import com.he1220.demo.pojo.User;
import org.springframework.web.bind.annotation.RequestBody;
import org.springframework.web.bind.annotation.RequestMapping;
import org.springframework.web.bind.annotation.RestController;RestController
public class RequestController {RequestMapping(/jsonParam)public String jsonParam(RequestBody User user){System.out.println(user);return ok~;}
}路径参数 通过请求URL直接传递参数使用{...}来标识该参数路径需要使用PathVariable获取参数路径 RestController
public class RequestController {RequestMapping(/path/{id}/{name})public String pathParam(PathVariable Integer id,PathVariable String name){System.out.println(id name);return ok~;}
}响应
ResponseBody 放在Controller方法上/类上 将方法返回值直接响应如果返回值类型是实体对象/集合,将会转换为JSON格式响应 RestController Controller ResponseBody 统一响应结果
目录结构如下 pojo.Result.java文件内容如下
package com.he1220.demo.pojo;/*** 统一响应结果封装类*/
public class Result {private Integer code ;//1 成功 , 0 失败private String msg; //提示信息private Object data; //数据 datapublic Result() {}public Result(Integer code, String msg, Object data) {this.code code;this.msg msg;this.data data;}public Integer getCode() {return code;}public void setCode(Integer code) {this.code code;}public String getMsg() {return msg;}public void setMsg(String msg) {this.msg msg;}public Object getData() {return data;}public void setData(Object data) {this.data data;}public static Result success(Object data){return new Result(1, success, data);}public static Result success(){return new Result(1, success, null);}public static Result error(String msg){return new Result(0, msg, null);}Overridepublic String toString() {return Result{ code code , msg msg \ , data data };}
}RequestController.class内容如下
package com.he1220.demo.controller;import com.he1220.demo.pojo.Add;
import com.he1220.demo.pojo.Result;
import org.springframework.web.bind.annotation.RequestMapping;
import org.springframework.web.bind.annotation.RestController;RestController
public class RequestController {RequestMapping(/getAddr)public Result getAddr(String province, String city){System.out.println(province);System.out.println(city);Add addr new Add();addr.setProvince(province);addr.setCity(city);return Result.success(addr);}
}测试结果如下
