toString 更优雅的实现方式

Posted 2023-01-12 程序员石磊

看看xxx的写法，不是很优雅

@Override
	public String toString() 
		return "FillRecordDetailEntity [id=" + id + ", fillRecordTotalId="
				+ fillRecordTotalId + ", businessInfoId=" + businessInfoId
				+ ", commitTime=" + commitTime + ", lastUpdateTime="
				+ lastUpdateTime + ", isISubmit=" + isISubmit
				+ ", isFinalValid=" + isFinalValid 
				+ ", infoCode=" + infoCode 
				+ ", handlerResult=" + handlerResult
				+ ", checkStatus=" + checkStatus +
				//", scanFileRecordEntity="
				//+ scanFileRecordEntity + 
				", fieldVlaueEntitySet="
				+ fieldVlaueEntitySet + "]";
	
	

要善于利用工具才可以提高效率，下面利用apache Commons Lang之toString()实现

• 给出实体类

public class Foo  
        private String name; 
        private int age; 
        private Bar bar; 

        public Foo(String name, int age)  
                this.name = name; 
                this.age = age; 
        

        //省略getter/setter方法 

• 通过反射方式实现toString();

@Override 
        public String toString()  
                return ReflectionToStringBuilder.toString(this); 
        

• 通过自定义格式方式实现

        @Override 
        public String toString()  
                return new ToStringBuilder(this, ToStringStyle.MULTI_LINE_STYLE) 
                                .append("name", name) 
                                .append("age", age) 
                                .append("bar", bar) 
                                .toString(); 
        

哪个更优化，更高效，一看便知
