我在我的程序中有以下代码片段,并且在与Maven集成之后,我正在运行SonarQube 5以进行代码质量检查.

但是,Sonar要求将封闭方法设为"静态"或删除此设置.方法是setApplicationContext.

如何删除此错误？为什么会出现这个错误？

public class SharedContext implements ApplicationContextAware {
public static final String REPORT_ENGINE_FACTORY = "reportEngineFactory";
private static ApplicationContext applicationContext;

public void setApplicationContext(ApplicationContext applicationContext)
        throws BeansException {
    SharedContext.applicationContext = applicationContext;
}

public static ApplicationContext getApplicationContext() {
    return applicationContext;
}

public Object getBean(String name) {
    return applicationContext.getBean(name);
} }

public String generateURLSafeToken(String username, char[] password) throws CredentialTokenException {
    this.tokenValid = false;

    String token = null;
    if ((username.length() < 1) || (username == null)) {
        throw new CredentialTokenException("Username cannot be an empty string or null.");
    }
    if ((password.length < 1) || (password == null)) {
        throw new CredentialTokenException("Password cannot be an empty or null.");
    }

我在第4行和第7行遇到此错误(用户名== null和密码== null)

我需要在我的代码中使用这一部分.我正在尝试isEmpty()而不是null,但也面临着问题.什么是解决此SONAR错误的替代方法或解决方案

我在我的程序中有以下代码片段,并且在与Maven集成之后,我正在运行SonarQube 5以进行代码质量检查.

但是,Sonar要求将此无用的赋值移除到局部变量"session".

@RequestMapping(value = "/logoff", method = RequestMethod.GET)
public String getLogoffPage(HttpServletRequest request, HttpServletResponse response) {
    logger.info(" Before Log Offf........ " + request.getSession().getId() );
    HttpSession session =request.getSession(true);
    request.getSession().invalidate();
    myApplication.logout();
    SecurityContextHolder.clearContext();
    session=null;                   
    return "login";
}
