[JAVA] A memorandum of addiction to Spring Boot2 x Doma2

About this page

I was a little addicted to developing with Spring Boot2 x Doma2, so I will leave it as a memorandum.

Our specs

Spring Boot 2.1.7 Java11 IntelliJ 2018.3 DOMA doma-spring-boot-starter:1.1.1 MySQL 5.7 gradle 5.4.1

[DOMA4019] SQL file not found in classpath

This error may occur even if the SQL file has the correct directory structure as shown below.

Example) --The location of the SQL file is correct UserRepostory findOne method src/main/xxx/domain/repository/UserResotiory.java src/main/resources/META-INF/xxx/domain/repository/UserResotiory/findOne.sql

solution)

Add the following to build.gradle

processResources.destinationDir = compileJava.destinationDir
compileJava.dependsOn processResources

Reference: https://github.com/domaframework/simple-boilerplate/blob/master/build.gradle

I get angry if I don't implement the Repository (Dao) interface at build time

The following error required a bean of type xxxxxRepository that could not be found. Consider defining a bean of type xxxxxx

solution)

1. It is assumed that the following settings are made in IntellJ (it should be done if Lombok is installed) In Preference> Build, Execution, Deployment> Annotation Processors Turn on Enable annotation processing

2. Annotate the Repository (Dao) interface with ConfigAutowireable

How to make DomaConfig

If you want to pass through even if there is an unknown column, you need to create Doma's Config class and override UnknownColumnHandler. (There should be other cases where Config is required) In the official document, the method of using SingletonConfig is at the top, but in the case of Spring Boot, an advanced method that matches the framework is required.

Solution example)

DomaConfig.java

@Configuration
public class DomaConfig implements Config {


    @Autowired
    private DomaAutoConfiguration domaAutoConfiguration;

    @Autowired
    private DataSource dataSource;

    @Override
    public DataSource getDataSource() {
        return dataSource;
    }

    @Override
    public UnknownColumnHandler getUnknownColumnHandler() {
        return new UnknownColumnHandler() {
            @Override
            public void handle(Query query, EntityType<?> entityType, String unknownColumnName) {
                //Override and crush
            }
        };
    }

    @Override
    public Dialect getDialect() {
        return domaAutoConfiguration.dialect();
    }

    @Bean
    @Primary
    @ConfigurationProperties(prefix = "spring.datasource")
    public DataSource primaryDataSource(DataSourceProperties properties) {
        return properties.initializeDataSourceBuilder().build();
    }
}

Remarks

I think MyBatis is common for Spring Boot 2 ORM, but I tried using Doma2 for the following reasons.

1. I want to separate Java and SQL
2. You don't have to write XML
