❶ java读写dbf文件

Java读取DBF文件，需要加载开源jar包JavaDBF.jar，然后使用里面的方法进行读写，示例如下：

packagesearch;
publicclassReadDBF{
publicstaticvoidmain(Stringargs[])

{
readDBF();
}
privatestaticvoidreadDBF()
{
try
{
System.out.println("正在读取文件！");

DBFReaderdbfreader=newDBFReader("D:\ZG2011格式.dbf");
for(intb=0;b<dbfreader.getFieldCount();b++)
{
if(b>0)
{System.out.print(",");}
System.out.print(dbfreader.getField(b).getName().trim().toUpperCase());

if(b==(dbfreader.getFieldCount()-1))
System.out.print("
");
}
for(inti=0;dbfreader.hasNextRecord();i++)
{
String[]aobj=dbfreader.nextRecordString();
for(intb=0;b<dbfreader.getFieldCount();b++)
{
if(b>0)
System.out.print(",");
System.out.print(aobj[b].trim());

if(b==(dbfreader.getFieldCount()-1))
System.out.print("
");

}
}
System.out.println("读取文件成功！");
}
catch(Exceptione)
{
	System.out.print(e.getMessage());
}
}

}

❷ java程序如何读取dbf文件 最好写上代码

publicclassRwdbf{

publicstaticvoidreadDBF(Stringpath)

{

InputStreamfis=null;
try
{
//读取文件的输入流
fis=newFileInputStream(path);
//根据输入流初始化一个DBFReader实例，用来读取DBF文件信息
DBFReaderreader=newDBFReader(fis);
//调用DBFReader对实例方法得到path文件中字段的个数
intfieldsCount=reader.getFieldCount();
System.out.println("字段数:"+fieldsCount);
//取出字段信息
for(inti=0;i<fieldsCount;i++)
{
DBFFieldfield=reader.getField(i);
System.out.println(field.getName());
}
Object[]rowValues;
//一条条取出path文件中记录
while((rowValues=reader.nextRecord())!=null)
{
for(inti=0;i<rowValues.length;i++)
{
System.out.println(rowValues[i]);
}
}
}
catch(Exceptione)
{
e.printStackTrace();
}
finally
{
try{
fis.close();
}catch(Exceptione){}
}
}publicstaticvoidwriteDBF(Stringpath)
{

OutputStreamfos=null;
try
{
//定义DBF文件字段
DBFField[]fields=newDBFField[3];
//分别定义各个字段信息，setFieldName和setName作用相同，
//只是setFieldName已经不建议使用
fields[0]=newDBFField();
//fields[0].setFieldName("emp_code");
fields[0].setName("semp_code");
fields[0].setDataType(DBFField.FIELD_TYPE_C);
fields[0].setFieldLength(10);

fields[1]=newDBFField();
//fields[1].setFieldName("emp_name");
fields[1].setName("emp_name");
fields[1].setDataType(DBFField.FIELD_TYPE_C);
fields[1].setFieldLength(20);

fields[2]=newDBFField();
//fields[2].setFieldName("salary");
fields[2].setName("salary");
fields[2].setDataType(DBFField.FIELD_TYPE_N);
fields[2].setFieldLength(12);
fields[2].setDecimalCount(2);

//DBFWriterwriter=newDBFWriter(newFile(path));

//定义DBFWriter实例用来写DBF文件
DBFWriterwriter=newDBFWriter();
//把字段信息写入DBFWriter实例，即定义表结构
writer.setFields(fields);
//一条条的写入记录
Object[]rowData=newObject[3];
rowData[0]="1000";
rowData[1]="John";
rowData[2]=newDouble(5000.00);
writer.addRecord(rowData);

rowData=newObject[3];
rowData[0]="1002";
rowData[1]="Rohit";
rowData[2]=newDouble(7350.00);
writer.addRecord(rowData);

//定义输出流，并关联的一个文件
fos=newFileOutputStream(path);
//写入数据
writer.write(fos);

//writer.write();
}catch(Exceptione)
{
e.printStackTrace();
}
finally
{
try{
fos.close();
}catch(Exceptione){}
}
}

publicstaticvoidmain(String[]args){
Stringpath="E:\tmp\2\xx.dbf";
try{
InputStreamfis=newFileInputStream(path);
DBFReaderreader=newDBFReader(fis);
intfieldsCount=reader.getFieldCount();
System.out.println("字段数:"+fieldsCount);

DBFField[]df=newDBFField[fieldsCount+2];
for(inti=0;i<fieldsCount;i++)
{
df[i]=reader.getField(i);
System.out.println("field"+i+":"+df[i].getName());
}
df[fieldsCount]=newDBFField();

DBFWriterwriter=newDBFWriter();
writer.setFields(df);

}

writer.addRecord(rowValues1);
}


path="E:\tmp\2\test2.dbf";

System.out.println("OVER");


}catch(FileNotFoundException|DBFExceptione){
