3:applicationContext.xml和之前的不一样
- <?xml version="1.0" encoding="UTF-8"?>
- <beans xmlns="http://www.springframework.org/schema/beans"
- xmlns:xsi="http://www.w3.org/2001/XMLSchema-instance"

4:一个实体类
- package com.qqw.entity;
- public class Student {
- private String name;
- private String sex;
- private Integer age;
- public Student() {
- super();
- // TODO Auto-generated constructor stub
- }
- public Student(String name, String sex, Integer age) {
- super();
- this.name = name;
- this.sex = sex;
- this.age = age;
- }
- public String getName() {
- return name;
- }
- public void setName(String name) {
- this.name = name;
- }
- public String getSex() {
- return sex;
- }
- public void setSex(String sex) {
- this.sex = sex;
- }
- public Integer getAge() {
- return age;
- }
- public void setAge(Integer age) {
- this.age = age;
- }
- }
5:在写接口前一些注解的概念参考这篇文章:jax-rs常用注解
接口StudentService.Java
- package com.qqw.webservice;
- import java.util.List;
- import javax.ws.rs.GET;
- import javax.ws.rs.Path;
- import javax.ws.rs.PathParam;
- import javax.ws.rs.Produces;
- import javax.ws.rs.core.MediaType;
- import com.qqw.entity.Student;
- @Path("/studentService")
- @Produces(MediaType.APPLICATION_JSON)
- public interface StudentService {
- //参看是否有这个学生
- @GET
- @Path("/status/{name}/{age}")
- public String getStatus(@PathParam("name") String name,@PathParam("age") Integer age);
- //通过id查看学生信息
- @GET
- @Path("/student/{index}")
- public Student getStudentById(@PathParam("index") Integer id);
- //查看所有学生信息
- @GET
- @Path("/student")
- public List<Student> getStudentList();
- }
6:接口实现类
- package com.qqw.webserviceImpl;
- import java.util.List;
- import java.util.ArrayList;
- import javax.ws.rs.GET;
- import javax.ws.rs.Path;
- import javax.ws.rs.PathParam;
- import org.springframework.stereotype.Component;
- import com.qqw.entity.Student;
- import com.qqw.webservice.StudentService;
- @Component("studentService")
- public class StudenntServiceImpl implements StudentService {
- @Override
- public Student getStudentById( Integer id) {
- Student student=null;
- if(id==1){
- student=new Student("张三", "男", 20);
- }else{
- student=new Student("李四娘", "女", 30);
- }
- return student;
- }
- @Override
- public List<Student> getStudentList() {
- List<Student> list=new ArrayList<Student>();
- Student student=new Student("张三", "男", 20);
- Student student1=new Student("李四娘", "女", 30);
- Student student2=new Student("李1娘", "女", 31);
- Student student3=new Student("李2娘", "女", 32);
- Student student4=new Student("李3娘", "女", 20);
- list.add(student);
- list.add(student1);
- list.add(student2);
- list.add(student3);
- list.add(student4);
- return list;
- }
- @Override
- public String getStatus(String name, Integer age) {
- String flag="FAULSE";
- if("tom狗".equals(name) && age==20){
- flag="TRUE";
- }
- return flag;
- }
- }
至此项目与spring整合完毕,把项目部署到tomcat。
测试第一个接口:http://localhost:8080/CXF_Spring_restful/webservice/studentService/status/tom狗/30,结果:
