如果在web.xml中未指明spring的配置配置文件名，默認在WEB-INF目錄下查找applicationContext.xml。下面包含property、spring、hibernate、cxf的配置：

<beans xmlns="http://www.springframework.org/schema/beans" xmlns:xsi="http://www.w3.org/2001/XMLSchema-instance"
       xmlns:aop="http://www.springframework.org/schema/aop" xmlns:context="http://www.springframework.org/schema/context"

        <property name="packagesToScan" value="com.pro.dao.hibernate.vo" />
    </bean>

<!-- 事務配置 -->

<!-- 配置cxf服務器的訪問地址：http://192.168.1.120:8000/ -->
    <bean id="endpoint" class="com.pro.CxfInterface"
        factory-bean="clientFactory" factory-method="create" />

    <bean id="clientFactory" class="org.apache.cxf.jaxws.JaxWsProxyFactoryBean">

        <property name="address" value="http://192.168.1.120:8000/" />
    </bean>

</beans>

Ioc控制的Bean默認是單例，如果要設置非單例在類前註明如下：

@Controller("employmentCtrl")
@Scope("prototype")
public class EmploymentCtrl{
@Resource
private EmploymentService employService;
......
}

業務類：

@Service("employService")
public class EmploymentServiceImpl implements EmploymentService {

@Resource
private EmploymentDao employDao;

@Override
@Transactional(isolation = Isolation.READ_COMMITTED, rollbackFor = Exception.class, timeout = 30)
public void addOrEditEmployment{......}

hibernate實體類例子如下(oracle爲例，也可設置爲native方便移植，屬性與表的字段一致即可)：

@Entity
@Table(name = "employment")
public class Employment implements Serializable {

    private static final long serialVersionUID = 6678401113364404864L;

    @Id
    @GeneratedValue(strategy = GenerationType.SEQUENCE, generator = "emp_seq")
    @SequenceGenerator(name = "emp_seq", sequenceName = "seq_emp", allocationSize = 1)
    private long id;
        ......

log4j有兩種文件配置方式：log4j.xml和.property配置文件，默認放置在WEB-INF/下面，以log4j.xml爲例配置如下：

<?xml version="1.0" encoding="UTF-8" ?>
<!DOCTYPE log4j:configuration SYSTEM "log4j.dtd">

<log4j:configuration xmlns:log4j="http://jakarta.apache.org/log4j/">

    <appender name="CONSOLE" class="org.apache.log4j.ConsoleAppender">
        <layout class="org.apache.log4j.PatternLayout">
            <param name="ConversionPattern" value="[%p] %d [%c.%M()] - %m%n"/>
        </layout>
    </appender>

    <appender name="FILE" class="org.apache.log4j.DailyRollingFileAppender">
        <param name="File" value="${root}logs/log.log" />
        <param name="Threshold" value="DEBUG" />
        <param name="Append" value="true" />
        <param name="DatePattern" value="'.'yyyy-MM-dd'.log'" />
        <layout class="org.apache.log4j.PatternLayout">
            <param name="ConversionPattern" value="[%p] %d [%c.%M] - %m%n"/>
        </layout>
    </appender>

    <logger name="org.apache">
        <level value="WARN"/>
    </logger>

    <logger name="org.springframework">
        <level value="WARN"></level>
    </logger>

    <logger name="java.sql">
        <level value="INFO"/>
    </logger>

    <logger name="com.mypro">
        <level value="DEBUG"/>
    </logger>

    <root>
        <level value="WARN"/>
        <appender-ref ref="CONSOLE"/>
        <appender-ref ref="FILE"/>
    </root>

</log4j:configuration>

log4j的日誌格式（Layout）說明如下：

符號         描述
----------------------------------------
%d       當前時間
%r           自程序開始後消耗的毫秒數
%t           表示日誌記錄請求生成的線程
%p           表示日誌語句的優先級
%r           與日誌請求相關的類別名稱
%c           日誌信息所在的類名
%M       日誌信息所在類的方法
%L       日誌信息所在方法的行數
%m%n         表示日誌信息的內容
