类 TrimStringType

java.lang.Object

org.hibernate.type.AbstractStandardBasicType<T>

org.hibernate.type.AbstractSingleColumnStandardBasicType<String>

com.github.mengweijin.quickboot.jpa.TrimStringType

所有已实现的接口:

Serializable, org.hibernate.type.BasicType, org.hibernate.type.DiscriminatorType<String>, org.hibernate.type.IdentifierType<String>, org.hibernate.type.LiteralType<String>, org.hibernate.type.ProcedureParameterExtractionAware<String>, org.hibernate.type.ProcedureParameterNamedBinder, org.hibernate.type.SingleColumnType<String>, org.hibernate.type.StringRepresentableType<String>, org.hibernate.type.Type

public class TrimStringType
extends org.hibernate.type.AbstractSingleColumnStandardBasicType<String>
implements org.hibernate.type.DiscriminatorType<String>

A type that maps between VARCHAR and String 情景：当数据库字段为 char(10) 类型时，使用jpa插入数据长度不够 10 时，数据库会自动追加空格； 当再次使用jpa查询数据时，返回到前台的该char字段（在java中使用String接收）就会多出一些空格，需要去除。 一般除非字段长度总是固定的，数据库才可以考虑使用char类型，否则请使用varchar类型，这样就可以避免这个问题。 如何使用：在java实体类对应的字段方法或属性添加 @Type(type = TrimStringType.TYPE) 或者 @Type(type = "com.mwj.mwjwork.framework.jpa.TrimStringType") 代码参考自 org.hibernate.type.StringType.java
