给所有实体类重写tostring方法
上代码
import java.io.Serializable; import org.apache.commons.lang3.builder.EqualsBuilder; import org.apache.commons.lang3.builder.HashCodeBuilder; import org.apache.commons.lang3.builder.ToStringBuilder; import org.apache.commons.lang3.builder.ToStringStyle; public abstract class BaseEntity implements Serializable{ /** * */ private static final long serialVersionUID = 1L; @Override public int hashCode() { return HashCodeBuilder.reflectionHashCode(this); } @Override public boolean equals(Object obj) { return EqualsBuilder.reflectionEquals(this, obj); } @Override public String toString() { return ToStringBuilder.reflectionToString(this, ToStringStyle.JSON_STYLE); }
然后所有的实体类继承这个方法即可
其中
JSON_STYLE是自从common3的3.4版本才开始有的
