再谈compass:集成站内搜索
时间:2011-01-05 javaeye lqw8668
前段时间已经写了一篇关于compass的文章,相信大家对compass也已经有了一定的了解
由于最近做的项目中涉及到了站内搜索,而且是基于JPA注解形式的,在网上找了好久,关于JPA集成compass的例子很少,有些也是基于 xml的,基于注解形式的甚是少,没有办法只有去compass的官网下载英文文档自己研究一下,花费了一下午时间调试出来,集成到项目中!
在这里给大家分享下,希望大家可以少走些弯路!
1.去官方网站下载compass的jar包,我用的的2.1版本

ProductInfo.java
Java代码
@Entity
@Searchable
public class ProductInfo implements Serializable{
private static final long serialVersionUID = -8860864584425256200L;
private Integer id;
/** 货号 **/
private String code;
/** 产品名称 **/
private String name;
/** 产品类型 **/
private ProductType type;
/** 产品样式 **/
private Set<ProductStyle> styles = new HashSet<ProductStyle>();
public ProductInfo() {}
@OneToMany(cascade={CascadeType.REMOVE,CascadeType.PERSIST}, mappedBy="product",fetch=FetchType.EAGER)
@OrderBy("visible desc, id asc")
@SearchableReference
public Set<ProductStyle> getStyles() {
return styles;
}
public void setStyles(Set<ProductStyle> styles) {
this.styles = styles;
}
@Id @GeneratedValue
@SearchableId
public Integer getId() {
return id;
}
public void setId(Integer id) {
this.id = id;
}
@Column(length=30)
@SearchableProperty(index = Index.TOKENIZED, store = Store.YES)
public String getCode() {
return code;

public void setCode(String code) {
this.code = code;

@Column(length=50,nullable=false)
@SearchableProperty(index = Index.TOKENIZED, store = Store.YES)
public String getName() {
return name;
}
public void setName(String name) {
this.name = name;
}
@ManyToOne(cascade=CascadeType.REFRESH,optional=false)
@JoinColumn(name="typeid")
@SearchableReference
public ProductType getType() {
return type;
}
public void setType(ProductType type) {
this.type = type;
}
@Override
public int hashCode() {
final int prime = 31;
int result = 1;
result = prime * result + ((id == null) ? 0 : id.hashCode());
return result;
}
@Override
public boolean equals(Object obj) {
if (this == obj)
return true;
if (obj == null)
return false;
if (getClass() != obj.getClass())
return false;
final ProductInfo other = (ProductInfo) obj;
if (id == null) {
if (other.id != null)
return false;
} else if (!id.equals(other.id))
return false;
return true;
}
}
