21. T H E S P R I N G R E S T S TA C K REST Essentials
22. GITHUB.COM/JOSHLONG/THE-SPRING-REST-STACK MOTIVATIONS FOR REST meanwhile, in the enterprise, somebody is using SOAP because it’s “SIMPLE”
23. GITHUB.COM/JOSHLONG/THE-SPRING-REST-STACK WHAT IS REST? REST is an architectural constraint based on HTTP 1.1, and created as part of Roy Fielding’s doctoral dissertation in 2000.
 
 It embraces HTTP. 
 It’s a style, not a standard http://en.wikipedia.org/wiki/Representational_state_transfer

24. GITHUB.COM/JOSHLONG/THE-SPRING-REST-STACK WHAT IS REST? REST has no hard and fast rules. REST is an architectural style, not a standard. REST uses Headers to describe requests & responses REST embraces HTTP verbs. (DRY)
25. GITHUB.COM/JOSHLONG/THE-SPRING-REST-STACK HTTP VERBS GET /users/21 GET requests retrieve information. GET can have side-effects (but it’s unexpected) GET can be conditional, or partial: 
 If-Modified-Since, Range !
26. GITHUB.COM/JOSHLONG/THE-SPRING-REST-STACK HTTP VERBS DELETE requests that a resource be removed, though the deletion doesn’t have to be immediate. DELETE /users/21
27. GITHUB.COM/JOSHLONG/THE-SPRING-REST-STACK HTTP VERBS POST requests that the resource do something with the enclosed entity POST can be used to create or update. 
 ! POST /users { “firstName”: “Juergen” }
28. GITHUB.COM/JOSHLONG/THE-SPRING-REST-STACK HTTP VERBS PUT requests that the entity be stored at a URI PUT can be used to create or update. PUT /users/21 { “firstName”: “Juergen” }
29. GITHUB.COM/JOSHLONG/THE-SPRING-REST-STACK STATUS CODES status codes convey the result of the server’s attempt to satisfy the request. 
 
 Categories: 1xx: informational
 2xx: success
 3xx: redirection
 4xx: client error 
 5xx: server error 

30. GITHUB.COM/JOSHLONG/THE-SPRING-REST-STACK STATUS CODES 200 OK - Everything worked ! 201 Created - Returns a Location header for new resource ! 202 Accepted - server has accepted the request, but it is not yet complete. Status URI optionally conveyed in Location header
31. GITHUB.COM/JOSHLONG/THE-SPRING-REST-STACK STATUS CODES 400 Bad Request - Malformed Syntax. Retry with change. ! 401 Unauthorized - authentication is required 
 403 Forbidden - server has understood, but refuses request
 
 404 Not Found - server can’t find a resource for URI 
 406 Incompatible - incompatible Accept headers specified
 409 Conflict - resource conflicts with client request
32. GITHUB.COM/JOSHLONG/THE-SPRING-REST-STACK CONTENT NEGOTIATION Clients and services must agree on a representation media type through content negotiation. ! Client specifies what it wants through Accept header 
 Server specifies what it produces through Content-Type header !
33. GITHUB.COM/JOSHLONG/THE-SPRING-REST-STACK CONTENT NEGOTIATION If no match is made, the client will receive a 406 Not Acceptable
34. GITHUB.COM/JOSHLONG/THE-SPRING-REST-STACK CONTENT NEGOTIATION Spring MVC supports multiple types of content negotiation through its ContentNegotiationStrategy: e.g., Accept header, URL extension, request parameters, or a fixed type

35. GITHUB.COM/JOSHLONG/THE-SPRING-REST-STACK SOME REST POWER TOOLS Advanced REST Client
36. GITHUB.COM/JOSHLONG/THE-SPRING-REST-STACK SOME REST POWER TOOLS Poster
37. GITHUB.COM/JOSHLONG/THE-SPRING-REST-STACK SOME REST POWER TOOLS ➜ ~ curl -X POST -u android-crm:123456 http://localhost:8080/oauth/token \
 -H "Accept: application/json" \

38. T H E S P R I N G R E S T S TA C K Towards Hypermedia
39. GITHUB.COM/JOSHLONG/THE-SPRING-REST-STACK THE MATURITY MODEL The Richardson Maturity Model is a way to grade your API according to the REST constraints with 4 levels of increasing compliance ! http://martinfowler.com/articles/richardsonMaturityModel.html
40. GITHUB.COM/JOSHLONG/THE-SPRING-REST-STACK THE MATURITY MODEL The Richardson Maturity Model 
 
 Level 0: swamp of POX
 http://martinfowler.com/articles/richardsonMaturityModel.html Uses HTTP mainly as a tunnel through one URI
 e.g., SOAP, XML-RPC
 
 Usually features on HTTP verb (POST)

41. GITHUB.COM/JOSHLONG/THE-SPRING-REST-STACK THE MATURITY MODEL The Richardson Maturity Model 
 
 Level 1: resources
 http://martinfowler.com/articles/richardsonMaturityModel.html Multiple URIs to distinguish related nouns 
 e.g., /articles/1, /articles/2, vs. just /articles
 

42. GITHUB.COM/JOSHLONG/THE-SPRING-REST-STACK THE MATURITY MODEL The Richardson Maturity Model 
 
 Level 2: HTTP verbs
 http://martinfowler.com/articles/richardsonMaturityModel.html leverage transport-native properties to enhance service 
 e.g., HTTP GET and PUT and DELETE and POST
 
 Uses idiomatic HTTP controls like status codes, headers 

43. Demonstration Our first @RestController
44. GITHUB.COM/JOSHLONG/THE-SPRING-REST-STACK HATEOAS The Richardson Maturity Model 
 
 Level 3: Hypermedia Controls (aka, HATEOAS)
 http://martinfowler.com/articles/richardsonMaturityModel.html No a priori knowledge of service required
 Navigation options are provided by service and hypermedia controls
 
 Promotes longevity through a uniform interface
 

45. GITHUB.COM/JOSHLONG/THE-SPRING-REST-STACK HATEOAS Links provide possible navigations from a given resource ! Links are dynamic, based on resource state. ! <link href=“http://...:8080/users/232/customers” 
 rel= “customers”/> ! { href: “http://...:8080/users/232/customers”, rel: “customers” }
46. Demonstration Working with Hypermedia and 
 Spring HATEOAS
47. GITHUB.COM/JOSHLONG/THE-SPRING-REST-STACK SPRING DATA REST Spring Data REST simplifies the 
 generic data-centric @Controllers ! Builds on top of Spring Data Repository support: @RestResource (path = "users", rel = "users") 
 public interface UserRepository extends PagingAndSortingRepository<User, Long> { ! User findByUsername(@Param ("username") String username); !

54. GITHUB.COM/JOSHLONG/THE-SPRING-REST-STACK HANDLING ERRORS IN A REST API Developers learn to use an API through errors Extreme programming and Test-Driven development embrace this truth ! Errors introduce transparency
55. GITHUB.COM/JOSHLONG/THE-SPRING-REST-STACK STATUS CODES Status codes map to errors pick a meaningful subset of the 70+ status codes 200 - OK 
 201 - Created
 304 - Created - Not Modified
 400 - Bad Request 
 401 - Unauthorized
 403 - Forbidden
 404 - Not Found

60. T H E S P R I N G R E S T S TA C K API Versioning
61. GITHUB.COM/JOSHLONG/THE-SPRING-REST-STACK VERSIONING YOUR API Build a version into your API ! API versions can be dealt with one of two ways: through API URIs: https://api.foo.com/v1 through media types: application/vnd.company.urapp-v3+json
62. T H E S P R I N G R E S T S TA C K Security
63. GITHUB.COM/JOSHLONG/THE-SPRING-REST-STACK SPRING SECURITY Security is hard. Don’t reinvent the wheel! ! Things to worry about when developing web applications? EVERYTHING ! (cross-site scripting, session fixation, identification, authorization, and authentication, encryption, and SO much more.)
64. GITHUB.COM/JOSHLONG/THE-SPRING-REST-STACK SPRING SECURITY Spring Security is a modern security framework for a modern age ! Authentication is valid? Authentication Mechanism collects the details client submits authentication credentials Store Authentication in SecurityContextHolder No - retry! Yes process original request
65. GITHUB.COM/JOSHLONG/THE-SPRING-REST-STACK SPRING SECURITY Spring Security is a modern security framework for a modern age ! Authentication is valid? Authentication Mechanism collects the details client submits authentication credentials Store Authentication in SecurityContextHolder No - retry! Yes process original request Authentication Mechanism collects the details! ! AuthenticationRequest is sent to AuthenticationManager! ! (passes it through a chain of AuthenticationProviders)! ! AuthenticationProvider asks a UserDetailsService for a UserDetails! ! The UserDetails object is used to build an Authentication object! ! !
66. Demonstration adding a Spring Security sign in form to a regular application ! !
67. GITHUB.COM/JOSHLONG/THE-SPRING-REST-STACK SECURING REST SERVICES Usernames and Passwords ! If you can trust the client to keep a secret like a password, then it can send the password using: 
 ...HTTP Basic - passwords are sent plaintext! ... HTTP Digest - hashed passwords, but still plaintext. 
 SSL/TLS encryption helps prevent man-in-the-middle attacks
68. GITHUB.COM/JOSHLONG/THE-SPRING-REST-STACK SSL AND TLS So, SSL/TLS is...? ! an implementation of public key cryptography: ! ! ! public key cryptography only works because we all agree to trust well known root CAs so trust! wow
69. GITHUB.COM/JOSHLONG/THE-SPRING-REST-STACK SSL AND TLS SSL/TLS is used routinely to verify the identify of servers. ! Normally, the client confirms the server, but the server rarely requires the client to transmit a certificate. ! It’s easy enough to setup SSL/TLS on your web server. !
70. Demonstration Setting up SSL/TLS with embedded Apache Tomcat 7 and Spring Boot ! !
71. GITHUB.COM/JOSHLONG/THE-SPRING-REST-STACK SSL AND TLS SSL/TLS can be used to identify the client to the server, through mutual authentication. ! ! browser/client must send their certificate, as well. @Override protected void configure(HttpSecurity http) throws Exception { http .authorizeRequests() .anyRequest().authenticated() .and() .x509(); }
72. @Configuration @EnableWebMvcSecurity public class SecurityConfig extends WebSecurityConfigurerAdapter { ! @Autowired public void configureGlobal(AuthenticationManagerBuilder auth) throws Exception { auth. inMemoryAuthentication() .withUser("mia").password("password").roles("USER").and() .withUser("mario").password("password").roles("USER","ADMIN"); } ! @Override protected void configure(HttpSecurity http) throws Exception { http .authorizeRequests() .anyRequest().authenticated() .and() .x509(); } }
73. Demonstration X509 Java configuration demo ! !
74. GITHUB.COM/JOSHLONG/THE-SPRING-REST-STACK THE TROUBLE WITH PASSWORDS Tim Bray says: Passwords don’t scale ! Too easy to compromise. ! Updating all your clients whenever you change your password would be a nightmare! !
75. GITHUB.COM/JOSHLONG/THE-SPRING-REST-STACK THE TROUBLE WITH PASSWORDS
76. GITHUB.COM/JOSHLONG/THE-SPRING-REST-STACK X-AUTH Most people just want their own clients to be able to talk securely to their own services. ! x-auth offers one way of achieving this based on tokens ! !
77. Demonstration A custom x-auth example
78. GITHUB.COM/JOSHLONG/THE-SPRING-REST-STACK OAUTH OAuth is a way for one (automated) process to securely identify itself to another ! Assumes a user context: ! “I authorize $CLIENTX to act on $USER_Y’s behalf” ! OAuth is a way of authorizing a client with particular access (scopes) !

92. GITHUB.COM/JOSHLONG/THE-SPRING-REST-STACK MICRO SERVICE ARCHITECTURE Micro Services ... ! Promote single responsibility principle ! Promote loosely coupled, focused services. (SOLID at the architecture level) ! Don’t like it? Throw it away! In object-oriented programming, the single responsibility principle states that every class should have a single responsibility, and that responsibility should be entirely encapsulated by the class. All its services should be narrowly aligned with that responsibility.! * * http://en.wikipedia.org/wiki/Single_responsibility_principle
