hi, I have saw code.
in situation 1, cause by `setterMethod.get().invoke(result,
entry.getValue());`, password type expect string type, I give integer type, my
solution is when occur IllegalArgumentException, exception message contains
yaml properties name.
occur exception code as follow:
```
/**
* Create data source.
*
* @return data source
*/
@SuppressWarnings({"unchecked", "rawtypes"})
@SneakyThrows(ReflectiveOperationException.class)
public DataSource createDataSource() {
DataSource result = (DataSource)
Class.forName(dataSourceClassName).getConstructor().newInstance();
Method[] methods = result.getClass().getMethods();
for (Entry<String, Object> entry : props.entrySet()) {
if (SKIPPED_PROPERTY_NAMES.contains(entry.getKey())) {
continue;
}
Optional<Method> setterMethod = findSetterMethod(methods,
entry.getKey());
if (setterMethod.isPresent()) {
setterMethod.get().invoke(result, entry.getValue());
}
}
Optional<JDBCParameterDecorator> decorator =
findJDBCParameterDecorator(result);
return decorator.isPresent() ? decorator.get().decorate(result) :
result;
}
```
I want modify to:
```
@SuppressWarnings({"unchecked", "rawtypes"})
@SneakyThrows(ReflectiveOperationException.class)
public DataSource createDataSource() {
DataSource result = (DataSource)
Class.forName(dataSourceClassName).getConstructor().newInstance();
Method[] methods = result.getClass().getMethods();
for (Entry<String, Object> entry : props.entrySet()) {
if (SKIPPED_PROPERTY_NAMES.contains(entry.getKey())) {
continue;
}
Optional<Method> setterMethodOpt = findSetterMethod(methods,
entry.getKey());
setterMethodOpt.map(method -> setDataSourceProperty(result,
method, entry.getValue(), entry.getKey()));
}
Optional<JDBCParameterDecorator> decorator =
findJDBCParameterDecorator(result);
return decorator.isPresent() ? decorator.get().decorate(result) :
result;
}
@SneakyThrows(ReflectiveOperationException.class)
private Void setDataSourceProperty(DataSource result, Method method,
Object value, String propertyName) {
try {
method.invoke(result, value);
return null;
} catch (IllegalArgumentException ex) {
throw new ShardingSphereConfigurationException(ex,
String.format("property %s configure error", propertyName));
}
}
public ShardingSphereConfigurationException(final Exception cause, final
String errorMessage) {
super(errorMessage, cause);
}
```
situation 2, I want to set origin cause exception look like more clear.
