话不多说,先看具体的例子:
文件目录结构:
web.xml
<?xml version="1.0" encoding="UTF-8"?> <web-app xmlns="http://java.sun.com/xml/ns/javaee" xmlns:xsi="http://www.w3.org/2001/XMLSchema-instance" xsi:schemaLocation="http://java.sun.com/xml/ns/javaee http://java.sun.com/xml/ns/javaee/web-app_2_5.xsd" version="2.5"> <display-name>platform</display-name> <!-- Spring ApplicationContext配置文件的路径,可使用通配符,多个路径用,号分隔 此参数用于后面的Spring Context Loader --> <context-param> <param-name>contextConfigLocation</param-name> <param-value>classpath:/applicationContext.xml,classpath:/applicationContext-rs.xml </param-value> </context-param> <!-- Character Encoding filter --> <filter> <filter-name>encodingFilter</filter-name> <filter-class>org.springframework.web.filter.CharacterEncodingFilter</filter-class> <init-param> <param-name>encoding</param-name> <param-value>utf-8</param-value> </init-param> </filter> <filter-mapping> <filter-name>encodingFilter</filter-name> <url-pattern>/*</url-pattern> </filter-mapping> <listener> <listener-class>org.springframework.web.context.ContextLoaderListener</listener-class> </listener> <!-- Spring 刷新Introspector防止内存泄露 --> <listener> <listener-class>org.springframework.web.util.IntrospectorCleanupListener</listener-class> </listener> <!-- Apache CXF Servlet 配置 --> <servlet> <servlet-name>CXFServlet</servlet-name> <servlet-class>org.apache.cxf.transport.servlet.CXFServlet</servlet-class> </servlet> <servlet-mapping> <servlet-name>CXFServlet</servlet-name> <url-pattern>/rest/*</url-pattern> </servlet-mapping> </web-app>
Spring的xml—applicationContext.xml
<?xml version="1.0" encoding="UTF-8"?> <beans xmlns="http://www.springframework.org/schema/beans" xmlns:xsi="http://www.w3.org/2001/XMLSchema-instance" xmlns:jee="http://www.springframework.org/schema/jee" xmlns:tx="http://www.springframework.org/schema/tx" xmlns:context="http://www.springframework.org/schema/context" xmlns:aop="http://www.springframework.org/schema/aop" xsi:schemaLocation="http://www.springframework.org/schema/beans http://www.springframework.org/schema/beans/spring-beans-3.2.xsd http://www.springframework.org/schema/tx http://www.springframework.org/schema/tx/spring-tx-3.2.xsd http://www.springframework.org/schema/jee http://www.springframework.org/schema/jee/spring-jee-3.2.xsd http://www.springframework.org/schema/context http://www.springframework.org/schema/context/spring-context-3.2.xsd" default-lazy-init="true"> <description>Spring公共配置文件</description> <!-- 使用annotation 自动注册bean,并保证@Required,@Autowired的属性被注入 --> <context:component-scan base-package="com.zd.daoImpl.*,com.zd.beanImpl.*,com.zd.serviceImpl.*,com.zd.service.*"> </context:component-scan> <bean id="dozerMapper" class="org.dozer.DozerBeanMapper" lazy-init="false" /> <!-- Matrix BPM --> <bean id="transactionInterceptor" class="org.springframework.transaction.interceptor.TransactionInterceptor"> <property name="transactionManager"> <ref bean="transactionManager" /> </property> <property name="transactionAttributes"> <props> <prop key="*">PROPAGATION_REQUIRED,-Exception</prop> </props> </property> </bean> </beans>
RestFul的xml—applicationContext-rs.xml
<?xml version="1.0" encoding="UTF-8"?> <beans xmlns="http://www.springframework.org/schema/beans" xmlns:xsi="http://www.w3.org/2001/XMLSchema-instance" xmlns:jaxrs="http://cxf.apache.org/jaxrs" xmlns:context="http://www.springframework.org/schema/context" xsi:schemaLocation=" http://www.springframework.org/schema/beans http://www.springframework.org/schema/beans/spring-beans-2.5.xsd http://cxf.apache.org/jaxrs http://cxf.apache.org/schemas/jaxrs.xsd http://www.springframework.org/schema/context http://www.springframework.org/schema/context/spring-context.xsd"> <description>Rails CM 的所有RESTFUL 服务配置</description> <context:component-scan base-package="com.zd" /> <bean id="jsonProvider" class="org.codehaus.jackson.jaxrs.JacksonJsonProvider"></bean> <jaxrs:server id="restContainer" address="/"> <jaxrs:inInterceptors> </jaxrs:inInterceptors> <jaxrs:serviceBeans> <ref bean="userinfoServiceImpl" /> </jaxrs:serviceBeans> </jaxrs:server> </beans>
实体:
package com.zd.entity; import java.io.Serializable; /** 系统用户表 **/ public class UserInfo implements Serializable { private String id; private String name;// 用户姓名 private String sex;// 性别 private String idNo;//身份证号码 private String account;// 账号 private String pwd;// 密码 public String getId() { return id; } public void setId(String id) { this.id = id; } public String getName() { return name; } public void setName(String name) { this.name = name; } public String getAccount() { return account; } public void setAccount(String account) { this.account = account; } public String getPwd() { return pwd; } public void setPwd(String pwd) { this.pwd = pwd; } public String getSex() { return sex; } public void setSex(String sex) { this.sex = sex; } public String getIdNo() { return idNo; } public void setIdNo(String idNo) { this.idNo = idNo; } }
构建的XML实体:
package com.zd.dtd; import javax.xml.bind.annotation.XmlAccessType; import javax.xml.bind.annotation.XmlAccessorType; import javax.xml.bind.annotation.XmlElement; import javax.xml.bind.annotation.XmlRootElement; import javax.xml.bind.annotation.XmlType; @XmlRootElement(name="UserInfoDTO") @XmlAccessorType(XmlAccessType.PROPERTY) @XmlType public class UserInfoDTD { private String id; private String name;// 用户姓名 private String sex;// 性别 private String idNo;//身份证号码 private String account;// 账号 private String pwd;// 密码 @XmlElement(name="id",required=false) public String getId() { return id; } public void setId(String id) { this.id = id; } @XmlElement(name="name",required=false) public String getName() { return name; } public void setName(String name) { this.name = name; } @XmlElement(name="account",required=false) public String getAccount() { return account; } public void setAccount(String account) { this.account = account; } @XmlElement(name="sex",required=false) public String getSex() { return sex; } public void setSex(String sex) { this.sex = sex; } @XmlElement(name="sex",required=false) public String getIdNo() { return idNo; } public void setIdNo(String idNo) { this.idNo = idNo; } @XmlElement(name="sex",required=false) public String getPwd() { return pwd; } public void setPwd(String pwd) { this.pwd = pwd; } }
接口服务层:
package com.zd.service; import javax.ws.rs.GET; import javax.ws.rs.Path; import javax.ws.rs.Produces; import javax.ws.rs.QueryParam; import javax.ws.rs.core.MediaType; import javax.ws.rs.core.Response; @Path("/Userinfo") public interface UserinfoService { /** * 根据id获取用户信息 * @param id 用户id * @return json数据 */ @GET @Path("/getUserinfo") @Produces({ "text/html;charset=utf-8", MediaType.TEXT_HTML }) public Response getBasicUserInfo(@QueryParam("id") String id); }
服务实现层:
package com.zd.serviceImpl; import javax.ws.rs.core.Response; import net.sf.json.JSONArray; import org.springframework.beans.factory.annotation.Autowired; import org.springframework.stereotype.Component; import com.zd.beanImpl.UserBeanImpl; import com.zd.dtd.UserInfoDTD; import com.zd.entity.UserInfo; import com.zd.service.UserinfoService; @Component public class UserinfoServiceImpl implements UserinfoService { @Autowired(required=true) private UserBeanImpl userBeanImpl; @Override public Response getBasicUserInfo(String id) { UserInfo userInfo = userBeanImpl.getUserInfo(id); UserInfoDTD userDTD=new UserInfoDTD(); userDTD.setSex(userInfo.getSex()); userDTD.setId(userInfo.getId()); userDTD.setIdNo(userInfo.getIdNo()); userDTD.setName(userInfo.getName()); userDTD.setPwd(userInfo.getPwd()); userDTD.setAccount(userInfo.getAccount()); //json转换 JSONArray jsonArray = JSONArray.fromObject(userInfo); return Response.ok(jsonArray.toString()).build(); } }
ServiceBean:
package com.zd.beanImpl; import org.springframework.beans.factory.annotation.Autowired; import org.springframework.stereotype.Service; import org.springframework.transaction.annotation.Transactional; import com.zd.daoImpl.UserinfoDaoImpl; import com.zd.entity.UserInfo; @Service //默认将类中的所有函数纳入事务管理. @Transactional public class UserBeanImpl { @Autowired(required=true) private UserinfoDaoImpl userinfoDaoImpl; public UserInfo getUserInfo(String id){ UserInfo userInfo=userinfoDaoImpl.getUserinfo(id); return userInfo; } }
Dao:
package com.zd.daoImpl; import org.springframework.stereotype.Repository; import org.springframework.transaction.annotation.Transactional; import com.zd.entity.UserInfo; @Repository //默认将类中的所有函数纳入事务管理. @Transactional public class UserinfoDaoImpl { public UserInfo getUserinfo(String id){ UserInfo userInfo=new UserInfo(); userInfo.setAccount("zhudan"); userInfo.setId("1111"); userInfo.setId("520911188119186770"); userInfo.setName("朱丹"); userInfo.setPwd("1221"); userInfo.setSex("女"); return userInfo; } }
页面访问地址:
http://localhost:8080/restful/rest/Userinfo/getUserinfo
页面访问结果:
总结:
先由这个例子,宏观了解下Restful的服务搭建,Restful的细节东西再在以后的运用中深入理解
