restfeed-server-spring

Spring Boot support for a REST Feed server endpoint.

Getting Started

Go to start.spring.io and create an new application. Select these dependencies:

• Spring Web (to provide an HTTP endpoint)
• JDBC API (for database connectivity)

for testing, you might also want to add

• H2 Database

Then add this library to your pom.xml:

    <dependency>
      <groupId>org.restfeeds</groupId>
      <artifactId>restfeed-server-spring</artifactId>
      <version>0.0.1</version>
    </dependency>

The RestFeedServerAutoConfiguration adds all relevant beans.

Add these properties to your application.properties:

restfeed.server.feed=myfeed
restfeed.server.path=/myfeed
restfeed.server.limit=1000
restfeed.server.jdbc.table=feed

Next, make sure to have a valid schema for you database set up (use Flyway or the schema.sql file):

create table feed
(
    position identity primary key,
    id       varchar(1024) not null,
    type     varchar(1024),
    resource varchar(1024),
    method   varchar(1024),
    timestamp timestamp,
    data      clob
);

and make sure your database is connected in your application.properties:

spring.datasource.url=jdbc:h2:mem:testdb

Finally, make sure that your application adds new feed items by calling the FeedItemRepository#append method.

feedItemRepository.append(
    "myfeed",
    UUID.randomUUID().toString(),
    "application/vnd.org.example.resource",
    "/myresource/123",
    "PUT",
    Instant.now().toString(),
    data);

When you start the application, you can connect to http://localhost:8080/myfeed.

Security

Basic Auth is optionally supported.

Add the spring-boot-starter-security dependency to your pom.xml:

    <dependency>
      <groupId>org.springframework.boot</groupId>
      <artifactId>spring-boot-starter-security</artifactId>
    </dependency>

and specify a username and password in your application.properties:

# alice:secure123
restfeed.server.credentials[0].username=alice
restfeed.server.credentials[0].password={bcrypt}$2a$10$WWJ/p6BOga2R5TRb2LIy4OzlPNiwNM0/aikVKuQ74dKgs67xLIeGS

The password should be encoded, e. g. with BCrypt.
