jersey2 整合 spring + hibernate + log4j2

整合 spring

jersey2 官方还未正式支持 spring4, 但网上有好多支持方案，折腾了一圈后，还是用了 spring3;

pom 添加以下依赖配置

		<!-- Spring --> 
		<dependency>
			<groupId>org.springframework</groupId>
			<artifactId>spring-web</artifactId>
			<version>4.3.1.RELEASE</version>
		</dependency> 
		<dependency>
			<groupId>javax.servlet</groupId>
			<artifactId>javax.servlet-api</artifactId>
			<version>3.1.0</version>
			<scope>provided</scope>
		</dependency>
		<dependency>
			<groupId>org.glassfish.jersey.containers</groupId>
			<artifactId>jersey-container-servlet</artifactId>
		</dependency>
		<dependency>
			<groupId>org.glassfish.jersey.ext</groupId>
			<artifactId>jersey-spring3</artifactId>
		</dependency>
    </dependencies>

添加 JerseyConfig 类

package com.easymylife.app.sys;
 
import org.glassfish.jersey.server.ResourceConfig;
import org.glassfish.jersey.server.spring.scope.RequestContextFilter;


public class JerseyConfig extends ResourceConfig {

    public JerseyConfig() {
        register(RequestContextFilter.class);
        packages("com.easymylife.app.sys");
        //register(LoggingFeature.class);
    }
}

添加 SpringAnnotationConfig 类

package com.easymylife.app.sys;

import org.springframework.context.annotation.ComponentScan;
import org.springframework.context.annotation.Configuration;

/**
 * Spring configuration to include our services
 *
 */
@Configuration
@ComponentScan(basePackageClasses = {})
public class SpringAnnotationConfig {
}

然后在 main 中调用

        final JerseyConfig resourceConfig = new JerseyConfig();
        resourceConfig.property("contextConfig", new AnnotationConfigApplicationContext(SpringAnnotationConfig.class));
        
        final HttpServer server = GrizzlyHttpServerFactory.createHttpServer(URI.create(BASE_URI), resourceConfig, false);
        

就可以通过 @Autowired 注解进行注入

@Singleton
@Path("spring-resource")
@Service
public class SpringRequestResource {

    AtomicInteger counter = new AtomicInteger();


/*    @Autowired
    private GoodbyeService myGoodbyeService;*/
    
    @Autowired
    private ISaySthService saySthService;
    
    @GET
    @Path("saysth")
    @Produces(MediaType.TEXT_PLAIN)
    public String getSaySth(){
    	return this.saySthService.hello("Grissom");
    }
    
    @GET
    @Path("users")
    @Produces(MediaType.APPLICATION_JSON)
    public List<SysUser> getUsers(){
    	return this.saySthService.getUsers();
    }
    
}

整合 hibernate

pom 配置

	<!-- hibernate -->
		<dependency>
			<groupId>mysql</groupId>
			<artifactId>mysql-connector-java</artifactId>
			<version>5.1.21</version>
		</dependency>
		<dependency>
			<groupId>org.hibernate</groupId>
			<artifactId>hibernate-core</artifactId>
			<version>5.2.10.Final</version>
		</dependency>
		<dependency>
			<groupId>org.hibernate</groupId>
			<artifactId>hibernate-validator</artifactId>
			<version>5.4.0.Final</version>
		</dependency>

如果通过 JPA 方式打开数据库 Session， 则在 main/resources/META-INF/ 下添加 persistence.xml 配置,

<?xml version="1.0" encoding="UTF-8" ?>
<persistence xmlns="http://java.sun.com/xml/ns/persistence"
 xmlns:xsi="http://www.w3.org/2001/XMLSchema-instance"
 xsi:schemaLocation="http://java.sun.com/xml/ns/persistence
 http://java.sun.com/xml/ns/persistence/persistence_1_0.xsd" version="1.0">
	<persistence-unit name="mysqlJPA" transaction-type="RESOURCE_LOCAL">
		<properties>
			<property name="hibernate.dialect" value="org.hibernate.dialect.MySQL5Dialect" />
			<property name="hibernate.connection.driver_class" value="com.mysql.jdbc.Driver" />
			<property name="hibernate.connection.username" value="username" />
			<property name="hibernate.connection.password" value="yourpwd" />
			<property name="hibernate.connection.url" value="jdbc:mysql://www.yourdomain.cn:3306/dbname" />
			<property name="hibernate.max_fetch_depth" value="3" />
			<property name="hibernate.hbm2ddl.auto" value="update" />
		</properties>
	</persistence-unit>
</persistence>

访问数据库代码

        EntityManagerFactory factory = Persistence.createEntityManagerFactory("mysqlJPA");  
        EntityManager em = factory.createEntityManager();  
        em.getTransaction().begin();
        Query query = em.createQuery("From SysUser");
        List<SysUser> user = query.getResultList();

如果直接用 hibernate 创建 session, 则在 mian/resources 下添加 hibernate.cfg.xml

<?xml version="1.0" encoding="UTF-8"?>
<!DOCTYPE hibernate-configuration PUBLIC "-//Hibernate/Hibernate Configuration DTD 3.0//EN"
                                         "http://hibernate.sourceforge.net/hibernate-configuration-3.0.dtd">
<hibernate-configuration>
 <session-factory name="hibernateSessionFactory">
  <property name="hibernate.connection.driver_class">com.mysql.jdbc.Driver</property>
  <property name="hibernate.connection.username">usernae</property>
  <property name="hibernate.connection.password">pwd</property>
  <property name="hibernate.connection.url">jdbc:mysql://www.yourdomain.cn:3306/dbname</property>
  <property name="hibernate.dialect">org.hibernate.dialect.MySQLDialect</property>
  <property name="hibernate.show_sql">true</property>
  <property name="hibernate.format_sql">true</property>
<!--   <property name="hibernate.hbm2ddl.auto">create</property> -->
  <mapping class="com.easymylife.app.sys.SysUser"/>
 </session-factory>
</hibernate-configuration>

代码

        Configuration configuration = new Configuration();
        configuration.configure("hibernate.cfg.xml");
                
        sessionFactory = configuration.buildSessionFactory();
        Session session =  getInstance().sessionFactory.openSession();
        Query query = session.createQuery("from SysUser");
        List<SysUser> employees =  query.list();
        session.close();
        return employees;

整合 log4j2

pom

		<dependency>
			<groupId>org.apache.logging.log4j</groupId>
			<artifactId>log4j-api</artifactId>
			<version>2.8.2</version>
		</dependency>
		<dependency>
			<groupId>org.apache.logging.log4j</groupId>
			<artifactId>log4j-core</artifactId>
			<version>2.8.2</version>
		</dependency>

main/resources 下添加 log4j2.xml

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

<Configuration status="off" monitorInterval="1800">

    <properties>
        <property name="LOG_HOME">C:\logs</property>
        <property name="ERROR_LOG_FILE_NAME">error</property>

        <property name="DEBUG_LOG_FILE_NAME">debug</property>
    </properties>

        <Console name="Console" target="SYSTEM_OUT">

                                 fileName="${LOG_HOME}/${ERROR_LOG_FILE_NAME}.log"

                                 filePattern="${LOG_HOME}/${INFO_LOG_FILE_NAME}.log.%d{yyyy-MM-dd}.gz">

            </Policies>
            <DefaultRolloverStrategy max="20"/>
        </RollingRandomAccessFile>
    </Appenders>

    <Loggers>
