Before we test this out lets create a very basic Spring Boot Application with classes/interfaces to verify HTTPIE. The following assumes you have a Spring Boot application already created and it has maven dependancies as follows to enable JPA, Rest Repositories, H2 and Web support
Note: We are using Spring Boot 1.5.3 here
<parent> <groupId>org.springframework.boot</groupId> <artifactId>spring-boot-starter-parent</artifactId> <version>1.5.3.RELEASE</version> <relativePath/> <!-- lookup parent from repository --> </parent> <properties> <project.build.sourceEncoding>UTF-8</project.build.sourceEncoding> <project.reporting.outputEncoding>UTF-8</project.reporting.outputEncoding> <java.version>1.8</java.version> </properties> <dependencies> <dependency> <groupId>org.springframework.boot</groupId> <artifactId>spring-boot-starter-data-rest</artifactId> </dependency> <dependency> <groupId>org.springframework.boot</groupId> <artifactId>spring-boot-starter-data-jpa</artifactId> </dependency> <dependency> <groupId>org.hibernate</groupId> <artifactId>hibernate-entitymanager</artifactId> </dependency> <dependency> <groupId>com.h2database</groupId> <artifactId>h2</artifactId> <scope>runtime</scope> </dependency> </dependencies>
1. Create classes/interfaces as follows
Employee.java
package pivotal.io.boot.httpie.demo;
import javax.persistence.Entity;
import javax.persistence.GeneratedValue;
import javax.persistence.GenerationType;
import javax.persistence.Id;
@Entity
public class Employee
{
@Id
@GeneratedValue (strategy = GenerationType.AUTO)
private Long id;
private String firstName;
private String lastName;
private String job;
public Employee()
{
}
public Employee(String firstName, String lastName, String job) {
this.firstName = firstName;
this.lastName = lastName;
this.job = job;
}
public Long getId() {
return id;
}
public void setId(Long id) {
this.id = id;
}
public String getFirstName() {
return firstName;
}
public void setFirstName(String firstName) {
this.firstName = firstName;
}
public String getLastName() {
return lastName;
}
public void setLastName(String lastName) {
this.lastName = lastName;
}
public String getJob() {
return job;
}
public void setJob(String job) {
this.job = job;
}
@Override
public String toString() {
return "Employee{" +
"id=" + id +
", firstName='" + firstName + '\'' +
", lastName='" + lastName + '\'' +
", job='" + job + '\'' +
'}';
}
}
EmployeeRepository.java
package pivotal.io.boot.httpie.demo;
import org.springframework.data.jpa.repository.JpaRepository;
public interface EmployeeRepository extends JpaRepository <Employee, Long> {
}
EmployeeRest.java
package pivotal.io.boot.httpie.demo;
import org.apache.commons.logging.Log;
import org.apache.commons.logging.LogFactory;
import org.springframework.beans.factory.annotation.Autowired;
import org.springframework.web.bind.annotation.*;
import java.util.List;
@RestController
@RequestMapping ("/api/employee")
public class EmployeeRest
{
private static Log logger = LogFactory.getLog(EmployeeRest.class);
@Autowired
private EmployeeRepository employeeRepository;
@GetMapping("/emps")
public List<Employee> allEmployees()
{
return employeeRepository.findAll();
}
@GetMapping("/emp/{employeeId}")
public Employee findEmployee (@PathVariable Long employeeId)
{
Employee emp = employeeRepository.findOne(employeeId);
return emp;
}
@PostMapping("/emps")
public Employee createEmployee(@RequestBody Employee employee)
{
return employeeRepository.save(employee);
}
@DeleteMapping("/emps/{employeeId}")
public void deleteEmployee(@PathVariable Long employeeId)
{
Employee emp = employeeRepository.findOne(employeeId);
employeeRepository.delete(emp);
logger.info("Employee with id " + employeeId + " deleted...");
}
}
2. Run the Spring Boot Application which will run on port localhost:8080
