用Jersey+spring+hibernate构建RESTful服务

来源：互联网发布：mac mobi convert 编辑：程序博客网时间：2024/05/16 13:12

最近梳理了一下之前写的restful服务端，由于以前用NetBeans写的，时间久了感觉NetBeans真是KA、卡！！！

现在用eclipse重新梳理一下，现在把整体结构记录一下，快速搭建一个基本的项目服务架构出来。

一、创建一个Dynamic Web Project项目，项目结构如下图：

二、导入所需要的jar包，jar下载地址（https://pan.baidu.com/s/1eSA3zPo）

三、配置RestApplication.java文件

import org.codehaus.jackson.jaxrs.JacksonJsonProvider;
import org.glassfish.jersey.server.ResourceConfig;

public class RestApplication extends ResourceConfig {
public RestApplication() {

// 服务类所在的包路径
packages("resources包路径");
// 注册JSON转换器
register(JacksonJsonProvider.class);

}
}

四、配置applicationContext.xml文件

<?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:context="http://www.springframework.org/schema/context"

xmlns:aop="http://www.springframework.org/schema/aop" xmlns:tx="http://www.springframework.org/schema/tx"

xsi:schemaLocation="http://www.springframework.org/schema/beans

http://www.springframework.org/schema/beans/spring-beans-4.0.xsd

http://www.springframework.org/schema/context

http://www.springframework.org/schema/context/spring-context-4.0.xsd

http://www.springframework.org/schema/aop

http://www.springframework.org/schema/aop/spring-aop-4.0.xsd

http://www.springframework.org/schema/tx

http://www.springframework.org/schema/tx/spring-tx-4.0.xsd">

<context:annotation-config></context:annotation-config>

<context:component-scan base-package="com.zh.rest.service" />

<context:component-scan base-package="com.zh.rest.dao" />

<list>

<value>classpath:jdbc.properties</value>

</list>

</property>

</bean>

<bean id="c3p0DataSource" destroy-method="close"

class="com.mchange.v2.c3p0.ComboPooledDataSource">

</bean>

<bean id="sessionFactory"

class="org.springframework.orm.hibernate4.LocalSessionFactoryBean">

<list>

<value>com.zh.rest.model</value>

</list>

</property>

<props>

<prop key="hibernate.dialect">${hibernate.dialect}</prop>

<prop key="hibernate.hbm2ddl.auto">${hibernate.hbm2ddl.auto}</prop>

<prop key="hibernate.show_sql">${hibernate.show_sql}</prop>

<prop key="hibernate.format_sql">${hibernate.format_sql}</prop>

<prop key="hibernate.hbm2ddl.auto">${hibernate.hbm2ddl.auto}</prop>

</props>

</property>

</bean>

<bean id="txManager"

class="org.springframework.orm.hibernate4.HibernateTransactionManager">

</bean>

<tx:advice id="txAdvice" transaction-manager="txManager">

<tx:attributes>

<tx:method name="add*" propagation="REQUIRED" />

<tx:method name="save*" propagation="REQUIRED" />

<tx:method name="update*" propagation="REQUIRED" />

<tx:method name="delete*" propagation="REQUIRED" />

<tx:method name="modify*" propagation="REQUIRED" />

<tx:method name="*" propagation="REQUIRED" read-only="true" />

</tx:attributes>

</tx:advice>

<aop:config>

<aop:pointcut id="bizMethods" expression="execution(* com.zh.rest.service.*.*(..))" />

<aop:advisor advice-ref="txAdvice" pointcut-ref="bizMethods" />

</aop:config>

</beans>

五、配置web.xml文件

<?xml version="1.0" encoding="UTF-8"?>

<web-app xmlns:xsi="http://www.w3.org/2001/XMLSchema-instance"

xmlns="http://java.sun.com/xml/ns/javaee"

xsi:schemaLocation="http://java.sun.com/xml/ns/javaee http://java.sun.com/xml/ns/javaee/web-app_3_0.xsd"

id="WebApp_ID" version="3.0">

<display-name>AHRESTful</display-name>

<welcome-file-list>

<welcome-file>index.html</welcome-file>

</welcome-file-list>

<module-name>AHRESTful</module-name>

<context-param>

<param-name>contextConfigLocation</param-name>

<param-value>

classpath:applicationContext.xml

</param-value>

</context-param>

<listener-class>org.springframework.web.context.ContextLoaderListener</listener-class>

</listener>

<servlet-name>Way REST Service</servlet-name>

<servlet-class>org.glassfish.jersey.servlet.ServletContainer</servlet-class>

<init-param>

<param-name>javax.ws.rs.Application</param-name>

<param-value>com.zh.rest.RestApplication</param-value>

</init-param>

<load-on-startup>1</load-on-startup>

</servlet>

<servlet-mapping>

<servlet-name>Way REST Service</servlet-name>

<url-pattern>/app/rest/*</url-pattern>

</servlet-mapping>

</web-app>

六、配置数据库连接文件jdbc.properties

driverClass = com.microsoft.sqlserver.jdbc.SQLServerDriver

url = jdbc:sqlserver://数据库地址:数据库端口;databaseName=RestDemo

username = 数据库登录名

password =数据库密码

hibernate.dialect = com.zh.rest.util.SqlServer2008Dialect

hibernate.hbm2ddl.auto = true

hibernate.show_sql = true

hibernate.format_sql = true

hibernate.hbm2ddl.auto = validate

c3p0.pool.maxPoolSize=30

c3p0.pool.minPoolSize=3

c3p0.pool.initialPoolSize=5

c3p0.pool.acquireIncrement=3

c3p0.pool.automaticTestTable=C3P0TestTable

c3p0.pool.testConnectionOnCheckin=true

c3p0.pool.idleConnectionTestPeriod=18000

c3p0.pool.maxIdleTime=25000

c3p0.pool.testConnectionOnCheckout=true

c3p0.pool.autoCommitOnClose=false

至此，相关配置已经完成。

由于项目有些配置问题，如果需要完整项目demo，请留言，单独发送分享一下
