jersey2 整合 spring + hibernate + log4j2 - grissom007－IT工程師數位筆記本

整合 spring

jersey2 官方還未正式支持 spring4, 但網上有好多支持方案，折騰了一圈后，還是用了 spring3;

pom 添加以下依賴配置

        <!-- 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 類

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 類

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 中調用

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

就可以通過 @Autowired 注解進行注入

@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>

如果通過 JPA 方式打開數據庫 Session，則在 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>

訪問數據庫代碼

        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 創建 session, 則在 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>

代碼

        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>


    <Appenders>
        <Console name="Console" target="SYSTEM_OUT">
            <PatternLayout pattern="%d %-5p (%F:%L) - %m%n" />
        </Console>

        <RollingRandomAccessFile name="ErrorLog"
                                 fileName="${LOG_HOME}/${ERROR_LOG_FILE_NAME}.log"

        </RollingRandomAccessFile>
        <RollingRandomAccessFile name="InfoLog"
                                 fileName="${LOG_HOME}/${INFO_LOG_FILE_NAME}.log"
                                 filePattern="${LOG_HOME}/${INFO_LOG_FILE_NAME}.log.%d{yyyy-MM-dd}.gz">
            <PatternLayout
