 cid-web-------------------------------------------------------------------------

Library for integrating spt-development/spt-development-cid
into a web project.

Usage

Register the CorrelationIdFilter to initialise the correlation ID for each incoming request and return as a response
header. For example, in a Spring based project register as a bean.

@Bean
public FilterRegistrationBean<CorrelationIdFilter> correlationIdFilter() {
    final FilterRegistrationBean<CorrelationIdFilter> filterRegBean = new FilterRegistrationBean<>(
            // Constructor overloads allow the overiding of the correlation ID header and whether to use the 
            // request correlation ID header (if it exists) to initialise the correlation ID.
            new CorrelationIdFilter()
    );
    filterRegBean.setOrder(Ordered.HIGHEST_PRECEDENCE);
    filterRegBean.addUrlPatterns("/api/v1.0/*");
    return filterRegBean;
}

Register the MdcCorrelationIdFilter to add the correlation ID to the MDC;

@Bean
public FilterRegistrationBean<MdcCorrelationIdFilter> mdcCorrelationIdFilter(@Value("${spt.cid.mdc.cid-key:#{null}}") String mdcCidKey) {
    final FilterRegistrationBean<MdcCorrelationIdFilter> filterRegBean = new FilterRegistrationBean<>(
            new MdcCorrelationIdFilter()
    );
    // This bean must be registed after the CorrelationIdFilter.
    filterRegBean.setOrder(Ordered.HIGHEST_PRECEDENCE + 1);
    filterRegBean.addUrlPatterns("/api/v1.0/*");
    return filterRegBean;
}

Alternatively, if you are integrating the library into a Spring Boot project, add the
spt-development/spt-development-cid-web-spring-boot
starter to your project’s pom.

Building locally

To build the library, run the following maven command:

$ ./mvnw clean install

Release

To build a release and upload to Maven Central push to main.
