java读取properties文件中文乱码的解决方法 收藏
java读取properties文件时，如果包含中文，那么该中文字段读出为乱码。这是因为java中文件大多以UTF-8或GBK的方式保存，而java程序在读出properties文件时则采用unicode编码方式，这样自然会导致中文乱码情况的发生。
spring怎么读取properties这里，先重现一下该问题，然后给出解决方法。
读取properties的方法如下：
view plaincopy to clipboardprint?
public class TestPorperty {
private InputStream is;//用于读取（.properties）文件
private Properties prop;
private final String propPath="D:\\Documents and Settings\\Administrator\\桌面\\test.properties";
public TestPorperty() throws Exception{
prop=new Properties();
}
public String getProperties(String key) throws Exception{
is=new FileInputStream(propPath);
prop.load(is);
Property(key);
}
}
public class TestPorperty {
private InputStream is;//用于读取（.properties）文件
private Properties prop;
private final String propPath="D:\\Documents and Settings\\Administrator\\桌面\\test.properties";
public TestPorperty() throws Exception{
prop=new Properties();
}
public String getProperties(String key) throws Exception{
is=new FileInputStream(propPath);
prop.load(is);
Property(key);
}
}
源文件test.properties内容如下：
view plaincopy to clipboardprint?
name=测试
value=测试值
name=测试
value=测试值
测试用例如下（注：这里利用junit进行相关测试）
view plaincopy to clipboardprint?
@Test
public void testGetProperties() throws Exception{
TestPorperty tp=new TestPorperty();
Assert.assertEquals("测试", tp.getProperties("name"));
Assert.assertEquals("测试值", tp.getProperties("value"));
}
@Test
public void testGetProperties() throws Exception{
TestPorperty tp=new TestPorperty();
Assert.assertEquals("测试", tp.getProperties("name"));
Assert.assertEquals("测试值", tp.getProperties("value"));
}
执行该测试用例，结果如下：
view plaincopy to clipboardprint?
