Recentemente, comecei a trabalhar com o Ratpack e estou gostando bastante. Na maioria das vezes, fiz projetos r\u00e1pidos do zero. Mas gostaria de us\u00e1-lo em um aplicativo Spring Boot existente para substituir a parte tradicional do MVC. Na verdade, isso \u00e9 f\u00e1cil de fazer, pois tudo j\u00e1 foi pensado gra\u00e7as ao M\u00f3dulo de mola<\/a>.<\/p>\n

Se voc\u00ea acompanha este blog, talvez se lembre de uma postagem antiga sobre armazenamento, indexa\u00e7\u00e3o e pesquisa<\/a> arquivos com Couchbase<\/a> e Spring Boot. Usarei o c\u00f3digo relacionado<\/a> como exemplo. A ideia \u00e9 substituir o Spring MVC pelo Ratpack e tornar meus servi\u00e7os legados, s\u00edncronos e bloqueadores, ass\u00edncronos e n\u00e3o bloqueadores. O c\u00f3digo resultante est\u00e1 dispon\u00edvel em github<\/a> tamb\u00e9m.<\/p>\n

Adi\u00e7\u00e3o das depend\u00eancias corretas<\/h2>\n

Estou usando o Gradle. O Ratpack \u00e9 muito bem integrado a ele. Tudo o que voc\u00ea precisa fazer para adicionar um m\u00f3dulo \u00e9 adicionar a depend\u00eancia correta chamando ratpack.dependency(\"myFavoriteModule\")<\/code>. Portanto, em nosso caso, para adicionar suporte ao Spring Boot, voc\u00ea precisa adicionar ratpack.dependency(\"spring-boot\")<\/code>. Infelizmente, a vers\u00e3o gerenciada automaticamente pelo Ratpack \u00e9 inferior a 1.4.0.M3, que \u00e9 a vers\u00e3o que traz a configura\u00e7\u00e3o autom\u00e1tica do Couchbase. Portanto, desta vez terei que adicionar as depend\u00eancias manualmente.<\/p>\n

    dependencies {\r\n      compile ratpack.dependency(\"guice\"),\r\n              ratpack.dependency(\"rx\"),\r\n              ratpack.dependency(\"handlebars\"),\r\n              \"com.couchbase.client:java-client:2.3.1\",\r\n              \"org.springframework.boot:spring-boot-autoconfigure:1.4.0.M3\",\r\n              \"io.ratpack:ratpack-spring-boot:1.3.3\",\r\n              \"org.slf4j:slf4j-simple:1.7.12\",\r\n              \"org.codehaus.plexus:plexus-utils:3.0.21\",\r\n              \"commons-codec:commons-codec:1.10\" \r\n    }\r\n<\/code><\/pre>\n
O que voc\u00ea pode ver aqui \u00e9 que ratpack.dependency(\"spring-boot\")<\/code> \u00e9 um atalho para adicionar org.springframework.boot:spring-boot-autoconfigure:1.4.0.M3<\/code> e io.ratpack:ratpack-spring-boot:1.3.3<\/code>. O que este m\u00f3dulo oferece a voc\u00ea \u00e9 a capacidade de integrar um servidor Ratpack ao seu aplicativo Spring. Voc\u00ea poder\u00e1 recuperar o Spring @Beans do contexto do Ratpack e declarar manipuladores como configura\u00e7\u00e3o do Spring.<\/p>\n
Declarar a configura\u00e7\u00e3o do Ratpack<\/h2>\n
Uma coisa que voc\u00ea deve adorar no Spring Boot \u00e9 a configura\u00e7\u00e3o autom\u00e1tica. Voc\u00ea s\u00f3 precisa ter certeza de que o SDK do Couchbase est\u00e1 no classpath e que a propriedade spring.couchbase.bootstrap-hosts<\/code> \u00e9 declarado. Nesse momento, os Spring beans ser\u00e3o instanciados para um Bucket padr\u00e3o. E essa inst\u00e2ncia do bucket estar\u00e1 dispon\u00edvel como um bean ou no contexto do Ratpack. Portanto, voc\u00ea n\u00e3o precisa declarar nenhuma liga\u00e7\u00e3o para o Couchbase na camada do Ratpack.<\/p>\n
A primeira coisa que voc\u00ea tradicionalmente faz com o Ratpack \u00e9 iniciar um servidor e definir a configura\u00e7\u00e3o e os manipuladores. Aqui j\u00e1 temos um aplicativo Spring Boot em execu\u00e7\u00e3o. Todas as classes anotadas com @Configuration ser\u00e3o coletadas automaticamente e adicionadas \u00e0 configura\u00e7\u00e3o do aplicativo. A primeira etapa para declarar essa configura\u00e7\u00e3o \u00e9 criar uma classe que implemente RatpackServerCustomizer<\/em> e anot\u00e1-lo com @Confguration. Isso permite que voc\u00ea defina uma lista de manipuladores, associa\u00e7\u00f5es e configura\u00e7\u00e3o do servidor. No exemplo a seguir, estou registrando algumas propriedades do servidor e vinculando v\u00e1rias classes ao contexto do Ratpack. A propriedade 'server.maxContentLength' \u00e9 o tamanho m\u00e1ximo do arquivo que voc\u00ea pode carregar.<\/p>\n

O sistema de modelos de aplicativos depende do Handlebars, portanto, voc\u00ea precisa do HandlebarsModule. O FileHandler tratar\u00e1 de todas as chamadas para a API '\/file' e o StoredFileRenderer garantir\u00e1 que o StoredFile seja renderizado corretamente. As duas \u00faltimas associa\u00e7\u00f5es s\u00e3o para gerenciamento de erros.<\/p>\n
A coisa mais importante que est\u00e1 acontecendo aqui \u00e9 a fileAPI<\/code> que declara meu manipulador. Um manipulador define o que acontece quando um usu\u00e1rio acessa um determinado URL. Aqui associamos todas as chamadas '\/file\/*' \u00e0 classe FileHandler. Tamb\u00e9m definimos o comportamento para POST em '\/fulltext' e '\/n1ql'.<\/p>\n
O Ratpack usa promessas. Portanto, quando voc\u00ea analisa um formul\u00e1rio proveniente de uma solicita\u00e7\u00e3o POST, obt\u00e9m uma promessa. O que voc\u00ea pode ver em cada um desses POST \u00e9 que o SearchService \u00e9 obtido do contexto do Ratpack. Mesmo que ele nunca tenha sido vinculado na configura\u00e7\u00e3o. Isso ocorre porque os Spring beans est\u00e3o dispon\u00edveis no contexto como parte da integra\u00e7\u00e3o.<\/p>\n
A pr\u00f3xima etapa \u00e9 chamar esse servi\u00e7o de pesquisa que retorna um Observable. Podemos usar o m\u00f3dulo rx-java do Ratpack que fornece um wrapper para Observables. Ele envolver\u00e1 isso como uma promessa. Em seguida, voc\u00ea pode simplesmente renderizar a resposta.<\/p>\n
Nesse ponto, nos livramos de todos os arquivos Spring MVC controladores<\/a>. Como voc\u00ea pode ver, meu servi\u00e7o retorna um Observable. O que n\u00e3o \u00e9 o caso em meu aplicativo anterior.<\/p>\n
Migra\u00e7\u00e3o de servi\u00e7os para o Ratpack<\/h2>\n
A maioria dos meus servi\u00e7os depende do Couchbase. O SDK \u00e9 baseado no RxJava, portanto, \u00e9 muito f\u00e1cil converter a maioria deles em um modo ass\u00edncrono e sem bloqueio e fazer com que retornem Observable.<\/p>\n
Usando o RxJava<\/h3>\n
Este \u00e9 um exemplo muito simples. \u00c9 uma consulta N1QL que mapeia os resultados para uma lista de mapas. As duas primeiras linhas n\u00e3o mudam em nada, pois est\u00e3o definindo principalmente a consulta. Voc\u00ea pode ver que o mapeamento parece mais natural quando se usa o bucket s\u00edncrono na segunda vers\u00e3o.<\/p>\n
    public List<map<string, object=\"\">> searchN1QLFiles(String whereClause) {\r\n        N1qlQuery query = N1qlQuery.simple(\r\n                \"SELECT binaryStoreLocation, binaryStoreDigest FROM `default` WHERE type= 'file' \" + whereClause);\r\n        query.params().consistency(ScanConsistency.STATEMENT_PLUS);\r\n        N1qlQueryResult res = bucket.query(query);\r\n        List<map<string, object=\"\">> filenames = res.allRows().stream().map(row -> row.value().toMap())\r\n                .collect(Collectors.toList());\r\n        return filenames;\r\n    }\r\n<\/map<string,><\/map<string,><\/code><\/pre>\n
Torna-se<\/p>\n
    public Observable<map<string, object=\"\">> searchN1QLFiles(String whereClause) {\r\n        N1qlQuery query = N1qlQuery.simple(\r\n                \"SELECT binaryStoreLocation, binaryStoreDigest FROM `default` WHERE type= 'file' \" + whereClause);\r\n        query.params().consistency(ScanConsistency.STATEMENT_PLUS);\r\n        return bucket.async().query(query).flatMap(AsyncN1qlQueryResult::rows).map(r -> r.value().toMap());\r\n    }\r\n<\/map<string,><\/code><\/pre>\n
E quanto ao bloqueio de c\u00f3digo legado?<\/h3>\n
Alguns dos meus servi\u00e7os dependem de c\u00f3digo antigo e bloqueador. Embora n\u00e3o exista uma maneira m\u00e1gica de torn\u00e1-los n\u00e3o bloqueantes, podemos facilmente envolv\u00ea-los em uma Promise. Isso nos permitir\u00e1 us\u00e1-las facilmente nos manipuladores. Envolver a chamada de bloqueio \u00e9 muito f\u00e1cil, tudo o que voc\u00ea precisa fazer \u00e9 envolver sua fun\u00e7\u00e3o com \"Blocking.get()\". Aqui est\u00e1 um exemplo muito simples:<\/p>\n
    public String getSha1Digest(InputStream is) {\r\n        return DigestUtils.sha1Hex(is);\r\n    }\r\n<\/code><\/pre>\n
torna-se<\/p>\n
    public Promise getSha1Digest(InputStream is) {\r\n        return Blocking.get(() -> DigestUtils.sha1Hex(is));\r\n    }\r\n<\/code><\/pre>\n
Conclus\u00e3o<\/h2>\n
