ssh+compass实现收索-优快云博客

本文记录了使用Struts2、Hibernate、Spring与Compass集成的过程，重点介绍了在集成过程中遇到的常见问题及其解决方案，包括Spring与Hibernate的jar包冲突、对象注入失败等问题。

照着v512 刘伟老师做了一个ssh 集成compass 的小程序最后的感觉是compass 很好很强大，我把我其中遇到的问题写出来，也许大家也会遇到，省下不必要的麻烦。

我的类库是 struts2+ hibernate3.2+spring2.5+ compass2.1

第一个问题，也是让我最崩溃的问题

org.springframework.beans.factory.BeanCreationException: Error creating bean with name 'compassIndexBuilder' defined in ServletContext resource [/WEB-INF/applicationContext-compass.xml]: Cannot resolve reference to bean 'compassGps' while setting bean property 'compassGps'; nested exception is org.springframework.beans.factory.BeanCreationException: Error creating bean with name 'compassGps' defined in ServletContext resource [/WEB-INF/applicationContext-compass.xml]: Cannot resolve reference to bean 'compass' while setting bean property 'compass'; nested exception is org.springframework.beans.factory.BeanCreationException: Error creating bean with name 'compass' defined in ServletContext resource [/WEB-INF/applicationContext-compass.xml]: Cannot resolve reference to bean 'transactionManager' while setting bean property 'transactionManager'; nested exception is org.springframework.beans.factory.BeanCreationException: Error creating bean with name 'transactionManager' defined in ServletContext resource [/WEB-INF/applicationContext.xml]: Cannot resolve reference to bean 'sessionFactory' while setting bean property 'sessionFactory'; nested exception is org.springframework.beans.factory.BeanCreationException: Error creating bean with name 'sessionFactory' defined in ServletContext resource [/WEB-INF/applicationContext.xml]: Invocation of init method failed; nested exception is java.lang.NoSuchMethodError: org.objectweb.asm.ClassVisitor.visit(IILjava/lang/String;Ljava/lang/String;[Ljava/lang/String;Ljava/lang/String;)V

看到这么长的错，我首先感觉到的就是，自己的代码有问题，死劲的找没找到。在网上搜了一下发现原来这错挺常见，我就按别人的提示一个一个的试，最终在http://atao.iteye.com/blog/281282 找到了答案，是由于Spring中的“asm-2.2.3.jar”和Hibernate中的“asm.jar”包冲突。解决办法是移除Spring2.5 AOP Libraries中的“asm-2.2.3.jar”即可。可是让我头痛的是怎么移除呢？MyEclipse 6.5 上要想单独移除asm-2.2.3 是不可能的，只能连spring 2.5 aop Libraries 一块移除，然后重新添加，这次选择直接添加.jar文件到lib 目录，但是我就怎么呀找到那个选择直接添加.jar文件的窗口选项在哪里，后来没办法只好在发布以后删除发布完成以后tomcat 对应目录下的asm-2.2.3.jar 。第一个问题就这样勉强的解决了。

第二个问题，

java.lang.IllegalArgumentException: Original must not be null

有了这个问题，基本就能确定是spring 不能将对象注入的原因一般是找不到对应的set 方法，我的错误是没写下面红颜色的set 方法。

package com.cntion.example.action;

import java.util.List;

import com.cntion.example.model.Product;
import com.cntion.example.service.ProductManager;
import com.opensymphony.xwork2.ActionSupport;
import org.apache.struts2.ServletActionContext;
/**
 * @author hsmiel
 *
 */
public class ProductAction extends ActionSupport {
	private ProductManager productManager;
	private Product product;
	private String queryString;
	
	public ProductManager getProductManager() {
		return productManager;
	}
	public void setProductManager(ProductManager productManager) {
		this.productManager = productManager;
	}
	public Product getProduct() {
		return product;
	}
	public void setProduct(Product product) {
		this.product = product;
	}
	public String getQueryString() {
		return queryString;
	}
	public void setQueryString(String queryString) {
		this.queryString = queryString;
	}
	
	
	

	public String insert(){
		productManager.insertProduct(product);
		return SUCCESS;
	}
	
	public String search(){
		List result=productManager.searchProduct(queryString);
		ServletActionContext.getRequest().setAttribute("searchresults",result);
		return SUCCESS;
	}




}

下面是我实现的关键代码

1 每次启动自动生成索引 CompassIndexBuilder.java

package com.cntion.example.service.impl;

import org.compass.gps.CompassGps;
import org.springframework.beans.factory.InitializingBean;


/**
 * 通过quartz定时调度定时重建索引或自动随Spring ApplicationContext启动而重建索引的Builder.
 * 会启动后延时数秒新开线程调用compassGps.index()函数.
 * 默认会在Web应用每次启动时重建索引,可以设置buildIndex属性为false来禁止此功能.
 * 也可以不用本Builder, 编写手动调用compassGps.index()的代码.
 *
 */
public class CompassIndexBuilder implements InitializingBean {   
    // 是否需要建立索引，可被设置为false使本Builder失效.
    private boolean buildIndex = false;

    // 索引操作线程延时启动的时间，单位为秒
    private int lazyTime = 10;

    // Compass封装
    private CompassGps compassGps;

    // 索引线程
    private Thread indexThread = new Thread() {

        @Override
        public void run() {
            try {
                Thread.sleep(lazyTime * 1000);
                System.out.println("begin compass index...");
                long beginTime = System.currentTimeMillis();
                // 重建索引.
                // 如果compass实体中定义的索引文件已存在，索引过程中会建立临时索引，
                // 索引完成后再进行覆盖.
                compassGps.index();
                long costTime = System.currentTimeMillis() - beginTime;
                System.out.println("compss index finished.");
                System.out.println("costed " + costTime + " milliseconds");
            } catch (InterruptedException e) {
                e.printStackTrace();
            }
        }
    };

    /**
     * 实现<code>InitializingBean</code>接口，在完成注入后调用启动索引线程.
     *
     * @see org.springframework.beans.factory.InitializingBean#afterPropertiesSet()
     */
    public void afterPropertiesSet() throws Exception {
        if (buildIndex) {
            indexThread.setDaemon(true);
            indexThread.setName("Compass Indexer");
            indexThread.start();
        }
    }

    public void setBuildIndex(boolean buildIndex) {
        this.buildIndex = buildIndex;
    }

    public void setLazyTime(int lazyTime) {
        this.lazyTime = lazyTime;
    }

    public void setCompassGps(CompassGps compassGps) {
        this.compassGps = compassGps;
    }
}

4 struts.xml

<?xml version="1.0" encoding="UTF-8" ?>
<!DOCTYPE struts PUBLIC
    "-//Apache Software Foundation//DTD Struts Configuration 2.0//EN"
    "http://struts.apache.org/dtds/struts-2.0.dtd">

		</action>
		<action name="search" class="productBean" method="search">
			<result>searchResults.jsp</result>
		</action>


	</package>

</struts>

5 收索方法红颜色的地方是表示按照商品名称收索

	public List searchProduct(String queryString) {
		Compass compass=compassTemplate.getCompass();
		CompassSession session=compass.openSession();

		CompassHits hits=session.queryBuilder().queryString("name:"+queryString).toQuery().hits();
		List list=new ArrayList();
		
		for(int i=0;i<hits.length();i++){
			Product hit=(Product)hits.data(i);
			list.add(hit);
		}

		return list;
	}

6 实体类

package com.cntion.example.model;
import org.compass.annotations.*;

/**
 * Product entity.
 * 
 * @author MyEclipse Persistence Tools
 */
@Searchable
public class Product implements java.io.Serializable {

	// Fields
	@SearchableId
	private String id;
	@SearchableProperty(name="name")
	private String name;
	@SearchableProperty(name="price")
	private Double price;
	@SearchableProperty(name="brand")
	private String brand;
	@SearchableProperty(name="description")
	private String description;

	// Constructors

	/** default constructor */
	public Product() {
	}

	/** full constructor */
	public Product(String name, Double price, String brand, String description) {
		this.name = name;
		this.price = price;
		this.brand = brand;
		this.description = description;
	}

	// Property accessors

	public String getId() {
		return this.id;
	}

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

	public String getName() {
		return this.name;
	}

	public void setName(String name) {
		this.name = name;
	}

	public Double getPrice() {
		return this.price;
	}

	public void setPrice(Double price) {
		this.price = price;
	}

	public String getBrand() {
		return this.brand;
	}

	public void setBrand(String brand) {
		this.brand = brand;
	}

	public String getDescription() {
		return this.description;
	}

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

}

其中很多地方我还是不太明白。.....继续努力。
