Jeecg中通过Spring_AOP+注解方式实现日志的管理

转载;https://blog.csdn.net/ma451152002/article/details/77234236
Jeecg中通过Spring_AOP+注解方式实现日志的管理

一、设计思路

通过spring的aop切面功能，拦截到请求的所有的符合切面表达式的方法，判断是否含有注解标志，生成日志对象，然后通过aop的后置通知进行日志的持久化。

二、代码实现

    、工程结构：

、pom.xml增加aop依赖：

 <dependency>
          <groupId>org.springframework</groupId>
          <artifactId>spring-aop</artifactId>
          <version>4.1..RELEASE</version>
        </dependency>
        <dependency>
          <groupId>aspectj</groupId>
          <artifactId>aspectjrt</artifactId>
          <version>1.5.</version>
        </dependency>
        <dependency>
          <groupId>org.aspectj</groupId>
          <artifactId>aspectjweaver</artifactId>
          <version>1.8.</version>
        </dependency>
        <dependency>
          <groupId>aopalliance</groupId>
          <artifactId>aopalliance</artifactId>
          <version>1.0</version>
        </dependency>
        <dependency>
          <groupId>cglib</groupId>
          <artifactId>cglib</artifactId>
          <version>3.2.</version>
        </dependency> 

、定义我们的Log实体对象
package aop;

import java.util.Date;

import javax.persistence.Column;
import javax.persistence.Entity;
import javax.persistence.GeneratedValue;
import javax.persistence.Id;
import javax.persistence.Table;

import org.hibernate.annotations.DynamicInsert;
import org.hibernate.annotations.DynamicUpdate;
import org.hibernate.annotations.GenericGenerator;
import org.jeecgframework.core.common.entity.IdEntity;

@Entity
@Table(name="assess_log_test")
@DynamicInsert(true)
@DynamicUpdate(true)
@SuppressWarnings("serial")
public class Log  implements java.io.Serializable{
    /**
     * 日志id
     */
    private String id;

    /**
     * 当前操作人id
     */
    private String loginAccount;

    /**
     * 当前操作人ip
     */
    private String loginIp;

    /**
     * 操作请求的链接
     */
    private String actionUrl;

    /**
     * 执行的模块
     */
    private String module;

    /**
     * 执行的方法
     */
    private String method;

    /**
     * 执行操作时间
     */
    private Long actionTime;

    /**
     * 描述
     */
    private String description;

    /**
     * 执行的时间
     */
    private Date gmtCreate;

    /**
     * 该操作状态，1表示成功，-1表示失败！
     */
    private Short state;

    @Id
    @GeneratedValue(generator = "paymentableGenerator")
    @GenericGenerator(name="paymentableGenerator",strategy="uuid")
    @Column(name="id",nullable=false,length=)
    public String getId() {
        return id;
    }
    @Column(name="login_account",length=)
    public String getLoginAccount() {
        return loginAccount;
    }
    @Column(name="login_ip",length=)
    public String getLoginIp() {
        return loginIp;
    }
    @Column(name="action_url",length=)
    public String getActionUrl() {
        return actionUrl;
    }
    @Column(name="module",length=)
    public String getModule() {
        return module;
    }
    @Column(name="method",length=)
    public String getMethod() {
        return method;
    }
    @Column(name="action_time")
    public Long getActionTime() {
        return actionTime;
    }
    @Column(name="description",length=)
    public String getDescription() {
        return description;
    }
    @Column(name="gmt_create")
    public Date getGmtCreate() {
        return gmtCreate;
    }
    @Column(name="state")
    public Short getState() {
        return state;
    }

    public void setId(String id) {
        this.id = id;
    }

    public void setLoginAccount(String loginAccount) {
        this.loginAccount = loginAccount;
    }

    public void setLoginIp(String loginIp) {
        this.loginIp = loginIp;
    }

    public void setActionUrl(String actionUrl) {
        this.actionUrl = actionUrl;
    }

    public void setModule(String module) {
        this.module = module;
    }

    public void setMethod(String method) {
        this.method = method;
    }

    public void setActionTime(Long actionTime) {
        this.actionTime = actionTime;
    }

    public void setDescription(String description) {
        this.description = description;
    }

    public void setGmtCreate(Date gmtCreate) {
        this.gmtCreate = gmtCreate;
    }

    public void setState(Short state) {
        this.state = state;
    }

    @Override
    public String toString() {
        return "Log [id=" + id + ", loginAccount=" + loginAccount
                + ", loginIp=" + loginIp + ", actionUrl=" + actionUrl
                + ", module=" + module + ", method=" + method + ", actionTime="
                + actionTime + ", description=" + description + ", gmtCreate="
                + gmtCreate + ", state=" + state + "]";
    }

}

.定义注解对象
package aop;

import java.lang.annotation.Documented;
import java.lang.annotation.ElementType;
import java.lang.annotation.Retention;
import java.lang.annotation.RetentionPolicy;
import java.lang.annotation.Target;

/**
 * 日志记录
 *
 *  @author mgj
 *    @date 2017-8-11 上午10:53:19
 */
@Target({ElementType.PARAMETER,ElementType.METHOD})
@Retention(RetentionPolicy.RUNTIME)
@Documented
public @interface SystemLog {
    String module() default "";
    String methods() default "";
}
.定义aop界面拦截方法
 package aop;

    @Around("controllerAspect()")
    public Object around(ProceedingJoinPoint pjp) throws Throwable{
        HttpServletRequest request = ((ServletRequestAttributes)RequestContextHolder.getRequestAttributes())
                                        .getRequest();
        //获得当前用户
        TSUser user = ResourceUtil.getSessionUserName();
        String name = user.getRealName();
        log.setLoginAccount(name);

        //拦截的实体类

        if (!(sig instanceof MethodSignature)) {
            throw new IllegalArgumentException("该注解只能用于方法");
        }

        msig = (MethodSignature)sig;
        Class[] parameterTypes = msig.getMethod().getParameterTypes();

        Object object = null;
        Method method = null;

        try{
            method = target.getClass().getMethod(methodName, parameterTypes);
        }catch (Exception e) {

                SystemLog systemlog = method.getAnnotation(SystemLog.class);
                log.setModule(systemlog.module());
                log.setMethod(systemlog.methods());

     */
    private String getIp(HttpServletRequest request){
        if (request.getHeader("x-forwarded-for") == null) {
            return request.getRemoteAddr();
        }
        return request.getHeader("x-forwarded-for");
    }

}

.增加aop自动扫描配置

（）打开spring-mvc.xml文件，增加aop上下文

   如下：
 <?xml version="1.0" encoding="UTF-8"?>
<beans xmlns="http://www.springframework.org/schema/beans"
    xmlns:mvc="http://www.springframework.org/schema/mvc"
    xmlns:xsi="http://www.w3.org/2001/XMLSchema-instance"
    xmlns:p="http://www.springframework.org/schema/p"
    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-3.0.xsd
       http://www.springframework.org/schema/context
        http://www.springframework.org/schema/context/spring-context-3.0.xsd
         http://www.springframework.org/schema/mvc
        http://www.springframework.org/schema/mvc/spring-mvc-3.0.xsd
        http://www.springframework.org/schema/aop
       http://www.springframework.org/schema/aop/spring-aop-3.0.xsd  ">

（）增加aop自动扫描并实例化bean
 <aop:aspectj-autoproxy proxy-target-class="true" />
<bean id="logAopAction" class="aop.LogAopAction"></bean>

.持久化Log实体的xml配置，使用自动扫描class的形式进行配置。打开spring-mvc-hibernate.xml文件，增加<value>aop.</value>
<bean id="sessionFactory"
        class="org.springframework.orm.hibernate4.LocalSessionFactoryBean">
        <property name="dataSource" ref="dataSource" />
        <property name="entityInterceptor" ref="hiberAspect" />
        <property name="hibernateProperties">
            <props>
                <!--<prop key="hibernate.hbm2ddl.auto">${hibernate.hbm2ddl.auto}</prop> -->
                <prop key="hibernate.dialect">${hibernate.dialect}</prop>
                <prop key="hibernate.hbm2ddl.auto">${hibernate.hbm2ddl.auto}</prop>
                <prop key="hibernate.show_sql">true</prop>
                <prop key="hibernate.format_sql">false</prop>
                <prop key="hibernate.temp.use_jdbc_metadata_defaults">false</prop>
            </props>
        </property>
        <!-- 注解方式配置 -->
        <property name="packagesToScan">
            <list>
                <value>org.jeecgframework.web.system.pojo.*</value>
                <value>org.jeecgframework.web.demo.entity.*</value>
                <value>org.jeecgframework.web.test.entity.*</value>
                <value>org.jeecgframework.web.cgform.entity.*</value>
                <value>org.jeecgframework.web.cgreport.entity.*</value>
                <value>aop.</value>
            </list>
        </property>
</bean>

.使用注解方式，配置日志，在访问的controller方法上，增加@SystemLog(module="区教师库登录",methods="区教师库的assessTeacherInfo()方法")配置
    /**
     * 教师库管理列表 页面跳转
     *
     * @return
     */
    @RequestMapping(params = "assessTeacherInfo")
    @SystemLog(module="区教师库登录",methods="区教师库的assessTeacherInfo()方法")
    public ModelAndView assessTeacherInfo(HttpServletRequest request) {
        return new ModelAndView("vote/backmanage/teachermanage/assessTeacherInfoList");
    }

.效果

三、注意事项
         .增加aop自动扫描包时，必须写到spring-mvc.xml内，不可写到spring-mvc-aop.xml文件中。因为spring-mvc.xml会比spring-mvc-aop.xml文先执行。
         .持久化Log实体，使用自动扫描class的形式进行配置时，规则如下
（）<value>aop.</value>，会解析为aop/*.class 或者 aop/xxx/*.class。即aop的包以及子包下的所有class。
            （2）<value>aop</value>，会解析为aop/*.class 。即aop的包下的所有class。
            （3）<value>aop.*</value>，会解析为 aop/xxx/*.class。即aop的子包下的所有class。

四、思考
1.需要深刻理解spring_mvc.xml文件的执行顺序。
2.需要深刻理解使用自动扫描class的形式的配置规则。
