Release 1.1

Version 1.1 includes new performance improvements and bug fixes.

Performance improvements

• All setup code has been moved to the static initializer method. If you follow the instructions in our documentation and archetypes to include the handler creation code in a static block you will see a drop in cold start latency.

private static SpringBootLambdaContainerHandler<AwsProxyRequest, AwsProxyResponse> handler;
static {
    try {
        handler = SpringBootLambdaContainerHandler.getAwsProxyHandler(Application.class);
    } catch (ContainerInitializationException e) {
        e.printStackTrace();
    }
}

• When using Spring profiles, we have added a new static method that receives a ConfigurableWebApplicationContext as well as a vararg list of profile names. Using this method will ensure that the application is initialized only once with the correct profile.

AnnotationConfigWebApplicationContext applicationContext = new AnnotationConfigWebApplicationContext();
applicationContext.register(PetStoreSpringAppConfig.class);
handler = SpringLambdaContainerHandler.getAwsProxyHandler(applicationContext, "profile-1", "profile-2");

• Setting profiles after the handler is initialized using the activateSpringProfiles method will cause the Spring context to reload and slow down the following request.
• Behind the scenes we moved the initialization of ObjectMapper, ObjectReader, and ObjectWriter to the LambdaContainerHandler constructor. This will ensure that they are initialized in the static code block.
• Archetype and examples for Spring now include the spring-context-indexer as a dependency.

Bug fixes

• Added a logback.xml configuration file for Spring and SpringBoot that sets the log level to ERROR. This addresses #134 to make Spring and SpringBoot applications testable with SAM Local.
• Added apiKeyId to the request identity model to address #136.
• New whitelist for hosts, ports, and base paths (#138). For applications that need to dynamically generate links, we've added the ability to read the forwarded host, and port headers. To secure this, developers have to explicitly whitelist custom domain names:

LambdaContainerHandler.getContainerConfig().addCustomDomain("api.myserver.com");

• Fixed query string encoding in Jersey (#140)
• Using body input stream instead of event body for form parameters (#141)
• Bumped Jackson dependency to 2.9.5 to address critical vulnerability (#139)
