[JAVA] Build a WEB system with Spring + Doma + H2DB Part 2

Introduction

Like last time, I will make it with reference to here.

Introducing Spring Tool Suite (STS) and Doma Tools

Introduce it because it is convenient for development

Introduction of STS

1. Search for STS in Help → ʻEclipse Marketplace` and install it.
2. Restart Eclipse after the installation is complete

Introduction of Doma Tools

1. Select http://dl.bintray.com/domaframework/eclipse/ in Help → Install new software. Enter
2. Check Doma Tools and Next
3. Restart Eclipse after installation is complete

Create a simple Select and Insert process

Creating Entity

1. Create an entity package
2. Create TestEntity in entity package

TestEntity.java

package com.tharao.createdesigndocuments.entity;

import org.seasar.doma.Entity;
import org.seasar.doma.GeneratedValue;
import org.seasar.doma.GenerationType;
import org.seasar.doma.Id;

@Entity
public class TestEntity {

	@Id
	@GeneratedValue(strategy = GenerationType.IDENTITY)
	public Integer id;
	public String name;

}

Create Dao

1. Create dao package
2. Create TestEntityDao in dao package

TestEntityDao.java

package com.tharao.createdesigndocuments.dao;

import java.util.List;

import org.seasar.doma.Dao;
import org.seasar.doma.Insert;
import org.seasar.doma.Select;
import org.seasar.doma.boot.ConfigAutowireable;
import org.springframework.transaction.annotation.Transactional;

import com.tharao.createdesigndocuments.entity.TestEntity;

@ConfigAutowireable
@Dao
public interface TestEntityDao {

	@Select
	List<TestEntity> selectAll();
	
	@Insert
	@Transactional
	int insert(TestEntity reservation);

}

Creating a Service

1. Create a service package
2. Create TestService in service package

TestService.java

package com.tharao.createdesigndocuments.service;

import java.util.List;

import org.springframework.beans.factory.annotation.Autowired;
import org.springframework.stereotype.Service;
import org.springframework.transaction.annotation.Transactional;

import com.tharao.createdesigndocuments.dao.TestEntityDao;
import com.tharao.createdesigndocuments.entity.TestEntity;

@Service
@Transactional
public class TestService {

	@Autowired
	TestEntityDao dao;

	public List<TestEntity> getAllEntities() {
		return dao.selectAll();
	}

}

Creating a Controller

1. Create controller package
2. Create a TestController in the controlle package

TestService.java

package com.tharao.createdesigndocuments.controller;

import java.util.List;

import org.springframework.beans.factory.annotation.Autowired;
import org.springframework.web.bind.annotation.RequestMapping;
import org.springframework.web.bind.annotation.RequestMethod;
import org.springframework.web.bind.annotation.RestController;

import com.tharao.createdesigndocuments.entity.TestEntity;
import com.tharao.createdesigndocuments.service.TestService;

@RestController
public class TestController {

	@Autowired
	TestService service;

	@RequestMapping(value = "test", method = RequestMethod.GET)
	public List<TestEntity> getEntities() {
		return service.getAllEntities();
	}

}

Creating a SQL file

1. Right-click on the selectAll method of the Dao interface and select Doma → Jump to Slq File to create it.
2. Add selectAll.sql

selectAll.sql

select
	id
	,name
from
	TestEntity
order by
	id asc

Creating an application

Enter initial data

CreateDesignDocumentsApplication.java

package com.tharao.createdesigndocuments;

import java.util.Arrays;
import java.util.List;

import org.springframework.beans.factory.annotation.Autowired;
import org.springframework.boot.CommandLineRunner;
import org.springframework.boot.SpringApplication;
import org.springframework.boot.autoconfigure.SpringBootApplication;
import org.springframework.context.annotation.Bean;

import com.tharao.createdesigndocuments.dao.TestEntityDao;
import com.tharao.createdesigndocuments.entity.TestEntity;

@SpringBootApplication
public class CreateDesignDocumentsApplication {

	public static void main(String[] args) {
		SpringApplication.run(CreateDesignDocumentsApplication.class, args);
	}

	@Autowired
	TestEntityDao testEntityDao;

	//Reservation Dao at startup#Insert initial data with insert
	@Bean
	CommandLineRunner runner() {
		return args -> Arrays.asList("spring", "spring boot", "doma").forEach(s -> {
			TestEntity r = new TestEntity();
			r.name = s;
			testEntityDao.insert(r);
		});
	}

}

Then set the SQL dialect in ʻapplication.properties`

application.properties

doma.dialect=h2

apt (annotation processing) settings

Follow the official Doma setup and set up apt.

1. View the Eclipse project properties and select Java Compiler → Annotation Processing

2. Check Allow project-specific settings

3. Set the generated source directory to .apt_generated

4. Add the following to processor options

   ey	value
   ao.subpackage	impl

5. Select Java Compiler → Annotation Processing → Factory Path

6. Check Allow project-specific settings

7. Add the doma jar to the annotation processor included plugin and JAR and press ʻOK`

Try to move

When I accessed [http: // localhost: 8080 / test](http: // localhost: 8080 / test), the data was safely displayed in JSON format.

Where I was addicted

I created the SQL files under src / main / resources, but all the files are set in the exclusion setting of src / main / resources in the Java build path of the project, created by DaoImpl Was not done. When I set the exclusion of src / main / resources to none, DaoImpl was successfully created and compiled.
