根据名称，获取省、市、区，编码 -- this.getClass().getResource 获取不到资源
java.io.FileNotFoundException: file:/xxx-SNAPSHOT.jar!/BOOT-INF/classes!/config/city_code_cn.json (No such file or directory)
String jsonPath = this.getClass().getResource(cityJsonPath).getPath();
如果用上面的写法，本地可以运行，发布后就获取不到了。
改成下面写法：
import org.springframework.core.io.Resource;
import org.springframework.core.io.ResourceLoader;
import org.springframework.util.FileCopyUtils;
import java.io.InputStream;
import java.nio.charset.StandardCharsets;
import java.util.HashMap;
//-----------------------------
@Autowired
private ResourceLoader resourceLoader;
public String getProvinceCode(String provinceName) {
try {
//发布后就获取不到了
//String jsonPath = this.getClass().getResource(cityJsonPath).getPath();
//String jsonString = FileUtil.readAsString(new File(jsonPath));
// 改成下面的获取资源方式
Resource resource = resourceLoader.getResource("classpath:" + cityJsonPath);
InputStream inputStream = resource.getInputStream();
byte[] bdata = FileCopyUtils.copyToByteArray(inputStream);
String jsonString = new String(bdata, StandardCharsets.UTF_8);
} catch (Exception ex) {
ex.printStackTrace();
}
return "";
}
如果是 Key/Value 可以通过下面的方法获取资源
// String filePath = "config/cn_message.properties";
protected Properties loadMessageAsProperties(String path) {
try (InputStream resourceAsStream = ClassUtils.getDefaultClassLoader().getResourceAsStream(path)) {
if (resourceAsStream == null) {
LOGGER.warn("business not file {}", path);
return null;
}
try (Reader reader = new InputStreamReader(resourceAsStream, "UTF-8")) {
Properties properties = new Properties();
properties.load(reader);
return properties;
}
} catch (IOException e) {
LOGGER.error("load message from properties {} failed", path, e);
return null;
}
}
