Question

这是我用来解决依赖关系的maven构建项目的pom.xml。

的pom.xml

<?xml version="1.0" encoding="UTF-8"?>
<project xmlns="http://maven.apache.org/POM/4.0.0" xmlns:xsi="http://www.w3.org/2001/XMLSchema-instance"

    </parent>

            </plugin>
        </plugins>

以下是我的示例应用程序的属性文件，我在使用applicationproperties和application-hsqldb.properties

application.properties

spring.profiles.active=hsqldb
# Hibernate
spring.jpa.hibernate.naming.physical-strategy=org.hibernate.boot.model.naming.PhysicalNamingStrategyStandardImpl
spring.jpa.properties.jadira.usertype.autoRegisterUserTypes=true

**application-hsqldb.properties**

# Hibernate
spring.jpa.hibernate.ddl-auto=validate

# Initialization
spring.datasource.schema=classpath:/data/hsqldb/schema.sql
spring.datasource.data=classpath:/data/hsqldb/data.sql

data.sql

INSERT INTO EMP(f_name, l_name) VALUES('Rajendar','Kumar');
INSERT INTO EMP(f_name, l_name) VALUES('Ramesh','Kumar');

schema.sql文件

DROP TABLE EMP IF EXISTS;

CREATE TABLE emp (
    id BIGINT GENERATED BY DEFAULT AS IDENTITY (START WITH 1, INCREMENT BY 1) NOT NULL,
    f_name VARCHAR(100) NOT NULL,
    l_name VARCHAR(100) NOT NULL,
    PRIMARY KEY (id)
    );

以下是我的休息服务的控制器，它有两个用于问候和从数据库读取数据的服务

import com.raj.hSQLdb.pojo.Employee;
import com.raj.hSQLdb.pojo.Greating;
import com.raj.hSQLdb.service.impl.ProcessEmpDataService;
@RestController
@RequestMapping("/app")
public class Controller{

    @Autowired
    private ProcessEmpDataService empDataService;

    private static final String template = "Hello, %s!";
    private final AtomicLong counter = new AtomicLong();

    @GetMapping("/greeting")
    public String sayHello(@RequestParam(value="name", defaultValue="Rajendar") String name) {
        return new Greating(String.valueOf(counter.incrementAndGet()), String.format(template, name)).toString();
    }


    @RequestMapping(value = {"/read"}, method = RequestMethod.GET)
    public ResponseEntity<?> read(Long id) {
        Employee response = empDataService.findOne(id);
        return new ResponseEntity<Employee>(response,HttpStatus.OK);
    }
}

实体

package com.raj.hSQLdb.pojo;

import java.io.Serializable;

import javax.persistence.Column;
import javax.persistence.Entity;
import javax.persistence.GeneratedValue;
import javax.persistence.GenerationType;
import javax.persistence.Id;
import javax.persistence.Table;
@Entity
@Table(name="emp")
public class Employee implements Serializable{
    private static final long serialVersionUID = 5667869092245806231L;

    @Id
    @GeneratedValue(strategy = GenerationType.AUTO)
    @Column(name = "id")
    private Long id;

    @Column(name = "f_name")
    private String firstName;
    @Column(name = "l_name")
    private String lastName;

    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;
    }

    @Override
    public String toString() {
        return "Employee [id=" + id + ", firstName=" + firstName + ", lastName=" + lastName + "]";
    }
}

** Greating **

package com.raj.hSQLdb.pojo;

public class Greating{

    public Greating(String code, String message) {
        this.code=code;
        this.message=message;
    }
    protected String code;
    private String message;
    public String getCode() {
        return code;
    }
    public String getMessage() {
        return message;
    }

}

存储库

package com.raj.hSQLdb.repository;

import org.springframework.data.jpa.repository.JpaRepository;
import org.springframework.stereotype.Repository;

import com.raj.hSQLdb.pojo.Employee;
@Repository
public interface EmployeeRepository extends JpaRepository<Employee, Long>{

}

服务

package com.raj.hSQLdb.service.impl;

import org.springframework.beans.factory.annotation.Autowired;
import org.springframework.stereotype.Component;
import com.raj.hSQLdb.pojo.Employee;
import com.raj.hSQLdb.repository.EmployeeRepository;

@Component
public class ProcessEmpDataService {

    @Autowired
    private EmployeeRepository repository;

    public Employee findOne(Long id) {
        Employee emp = repository.findOne(id);
        return emp;
    }
}

运行应用程序的主类

package com.raj.hSQLdb;

import org.springframework.boot.SpringApplication;
import org.springframework.boot.autoconfigure.SpringBootApplication;
import org.springframework.transaction.annotation.EnableTransactionManagement;

@SpringBootApplication
@EnableTransactionManagement
public class ServletInitializer {

    /**
     * @param args
     */
     public static void main(String[] args) {
            SpringApplication.run(ServletInitializer.class, args);
        }

}

带有spring-boot-starter-parent 1.4.0.RELEASE的HsqlDB
