声纳抱怨记录并重新抛出异常

Sonar complaining about logging and rethrowing the exception(声纳抱怨记录并重新抛出异常)

问题描述

我的程序中有以下代码，在将其与 Maven 集成后，我正在运行 SonarQube 5 以对其进行代码质量检查.

I have the following piece of code in my program and I am running SonarQube 5 for code quality check on it after integrating it with Maven.

但是，Sonar 抱怨我应该记录或重新抛出此异常.

However, Sonar is complaining that I should Either log or rethrow this exception.

我在这里缺少什么?我还没有记录异常吗?

What am I missing here? Am I not already logging the exception?

 private boolean authenticate(User user) {
        boolean validUser = false;
        int validUserCount = 0;
        try {
            DataSource dataSource = (DataSource) getServletContext().getAttribute("dataSource");
            validUserCount = new MasterDao(dataSource).getValidUserCount(user);
        } catch (SQLException sqle) {
            LOG.error("Exception while validating user credentials for user with username: " + user.getUsername() + " and pwd:" + user.getPwd());
            LOG.error(sqle.getMessage());
        }
        if (validUserCount == 1) {
            validUser = true;
        }
        return validUser;
    }

推荐答案

你应该这样做:

try {
    DataSource dataSource = (DataSource) getServletContext().getAttribute("dataSource");
    validUserCount = new MasterDao(dataSource).getValidUserCount(user);
} catch (SQLException sqle) {
    LOG.error("Exception while validating user credentials for user with username: " +
            user.getUsername() + " and pwd:" + user.getPwd(), sqle);
}

声纳不应该再打扰你了
