Spring - short note - 1- REST

Creating Rest Services

1.       Create Conroller class which is annotated by :  @Controller;

2.       For get methods:

    @RequestMapping(method = RequestMethod.GET,value = "/rami/{id}/{p}")

    @ResponseBody

    public String home(@PathVariable String id,@PathVariable int p) {

        return "Hello World!"+ id + "----"+p;

    }

Or:

@RequestMapping(method = RequestMethod.GET,value = "/rami")

    @ResponseBody

    public ClassA home3() {

        ClassA a = new ClassA();

        a.setName("ROMA");

        a.setAge(1112222);

        return a;

    }

For POST:

@RequestMapping(method = RequestMethod.POST,value = "/p1/")

     public    @ResponseBody  ClassA home2(@RequestBody ClassA id) {

        return id;

    }

3.      Create main * Spring Boot* :

public static void main(String[] args) throws Exception {

        SpringApplication.run(SampleController.class, args);

    }

With following in gradle file:

repositories {

    maven { url "http://repo.spring.io/libs-snapshot" }

    mavenCentral()

}

dependencies {

    testCompile group: 'junit', name: 'junit', version: '4.11'

    compile("org.springframework.boot:spring-boot-starter-web:1.0.2.RELEASE")

}




Working with Config
1. Create Config Class

@Configuration
public class InfiniSpanConfig {

    @Bean(name = "cache1")
    public Cache<String,String> namesCache() {

        Cache<String,String> cache = new DefaultCacheManager().getCache("test",true);
        return cache;
    }
}


2. Add @ComponentScan
3. in case of generic collection type autowiring use @Resource annotation instead of @Autowiring

    @Resource(name="cache1")
    private Cache<String,String> cache;
