Question

我是 Spring启动框架的新手，我需要设置Subject bean并在Audit过滤器中打印它的值。

以下是我正在使用的课程：

Subject.java

public class MyManager {
@Autowired
private Subject subject;

public void SetSubject () {
    subject = getSubject(); // Function return filled Subject bean having both values 
    //Printing subject here prints values for uid and tokenType
}
}

MyManager.java

public class Audit implements Filter {

@Autowired
private Subject subject;

@Override
public void init(FilterConfig filterConfig) throws ServletException {
}

@Override
public void doFilter(ServletRequest request, ServletResponse response,
        FilterChain chain) throws IOException, ServletException {
            System.out.println(Subject.toString()); // prints null
}

}

Audit.java

@Configuration
@ComponentScan(value = "com.org.project")
public class FilterConfig {

@Autowired
Environment environment;

@Bean
public FilterRegistrationBean oAuthRegistrationBean() {
    final FilterRegistrationBean registration = new FilterRegistrationBean();
    registration.addUrlPatterns("/*");
    registration.addInitParameter("role", "uc:admin");
    registration.setFilter(new AuthFilter()); //Subject and MyManager are part of this filter
    return registration;
}   

@Bean
public FilterRegistrationBean avrilAuditFilterRegistration() {
    FilterRegistrationBean registration = new FilterRegistrationBean();
    registration.setFilter(getAuditFilter());
    registration.addUrlPatterns("/*");
    registration.setName("Audit");
    return registration;
}

@Bean
public Filter getAuditFilter() {
    return new Audit();
}
}

FilterConfig.java

var expiry = "06-19";
var stillValid = (new Date("01-" + expiry).getTime() > new Date().getTime());

在setSubject（）函数中设置了Subject之后，在Audit过滤器类中获取了Subject的空值。

我有两个过滤器Auth和Audit。 First Auth过滤器进入了设置Subject bean的图片其次，审计过滤器需要访问主题bean，在这种情况下 null

在Spring引导中获取请求范围bean的空值
