环境：
idea 15.0.2
jersey 1.3
tomcat 7.0
maven 3.3.3
1.idea 基于maven 构建webapp 略过
2.项目构建完成之后pom.xml 文件加入项目所需包：
junit
junit
4.7
test
com.sun.jersey
jersey-core
1.3
com.sun.jersey
jersey-server
1.3
com.sun.jersey
jersey-client
1.3
log4j
log4j
1.2.14
javax.ws.rs
jsr311-api
1.1.1

3.创建pojo类 student：
@xmlrootelement
public class student {
private int id;
private string name;
private string dept;
public int getid() {
return id;
}
public student() {
}
public student(int id, string name, string dept) {
super();
this.id = id;
this.name = name;
this.dept = dept;
}
public void setid(int id) {
this.id = id;
}
public string getname() {
return name;
}
public void setname(string name) {
this.name = name;
}
public string getdept() {
return dept;
}
public void setdept(string dept) {
this.dept = dept;
}
}
同时创建资源类：
@path(/students)
public class restwsdemo {
private static logger logger = logger.getlogger(restwsdemo.class);
private static int index = 1;
private static map studentlist = new hashmap();
public restwsdemo() {
if(studentlist.size()==0) {
studentlist.put(index, new student(index++, frank, cs));
studentlist.put(index, new student(index++, jersey, math));
}
}
@get
@path({studentid})
@produces({mediatype.application_xml, mediatype.application_json})
public student getmetadata(@pathparam(studentid) int studentid) {
if(studentlist.containskey(studentid))
return studentlist.get(studentid);
else
return new student(0, nil, nil);
}
@get
@path(list)
@produces({mediatype.application_xml, mediatype.application_json})
public list getallstudents() {
list students = new arraylist();
students.addall(studentlist.values());
return students;
}
@post
@path(add)
@produces(text/plain)
public string addstudent(@formparam(name) string name,
@formparam(dept) string dept) {
studentlist.put(index, new student(index++, name, dept));
return string.valueof(index-1);
}
@delete
@path(delete/{studentid})
@produces(text/plain)
public string removestudent(@pathparam(studentid) int studentid) {
logger.info(receieving quest for deleting student: + studentid);
student removed = studentlist.remove(studentid);
if(removed==null) return failed!;
else return true;
}
@put
@path(put)
@produces(text/plain)
public string putstudent(@queryparam(studentid) int studentid,
@queryparam(name) string name,
@queryparam(dept) string dept
) {
logger.info(receieving quest for putting student: + studentid);
if(!studentlist.containskey(studentid))
return failed!;
else
studentlist.put(studentid, new student(studentid, name, dept));
return string.valueof(studentid);
}
}
创建完之后项目结构如图：
4.再web.xml 配置如下：
jerseyws
com.sun.jersey.spi.container.servlet.servletcontainer
com.sun.jersey.config.property.resourceconfigclass
com.sun.jersey.api.core.packagesresourceconfig
com.sun.jersey.config.property.packages
cz.service
1
jerseyws
/rest/*
其中 com.sun.jersey.config.property.packages 的属性值是你资源所在的包的路径
5.maven install 略过
6.启动tomcat 访问路径 http://localhost:8081/rest/students/list 就看以看到如下结果：
7.其他资源获取方式自行领悟、测试
