Spring Java Web プロジェクトの XML ベースの構成を JavaConfig に変換中です。
JPAを使用しています。そこで、必要な構成で追加の JavaConfig クラスを作成しました。しかし、何らかの理由で JPA 構成が失敗します。
これが私の[web.xml][1]です

これが私の主要な [JavaConfig クラス][2] です。
@Configuration
@EnableWebMvc
//@ImportResource("contoso-jpa.xml") //Import any existing xml context files
@Import(contosoJPA.class)
//@EnableTransactionManagement //substitute for <tx:annotation-driven/>
@ComponentScan({"com.my.contoso.webservices.rest", "com.my.contoso.services,com.my.contoso.dao"})
public class contosoConfig {
}
[JPA config][3] を使用した JavaConfig クラスは次のとおりです。
@Configuration
@EnableTransactionManagement
@EnableJpaRepositories //(basePackages = { "com.my.contoso.domain" })
public class contosoJPA {
@Bean
public DataSource dataSource() {
// return new EmbeddedDatabaseBuilder().setType(H2).build();
DriverManagerDataSource ds = new DriverManagerDataSource();
try {
ds.setDriverClassName("com.mysql.jdbc.Driver");
ds.setUsername("root");
ds.setPassword("");
ds.setUrl("jdbc:mysql://localhost:3306/contosodb");
} catch (Exception e) {
// logger.error(e.getMessage());
System.out.println(e);
}
return ds;
}
@Bean
public LocalContainerEntityManagerFactoryBean entityManagerFactory(DataSource dataSource, JpaVendorAdapter jpaVendorAdapter) {
LocalContainerEntityManagerFactoryBean lef = new LocalContainerEntityManagerFactoryBean();
lef.setDataSource(dataSource);
lef.setJpaVendorAdapter(jpaVendorAdapter);
lef.setPackagesToScan("com.my.contoso.domain");
lef.setPersistenceUnitName("contosoPU");
return lef;
}
@Bean
public JpaVendorAdapter jpaVendorAdapter() {
HibernateJpaVendorAdapter hibernateJpaVendorAdapter = new HibernateJpaVendorAdapter();
hibernateJpaVendorAdapter.setShowSql(false);
hibernateJpaVendorAdapter.setGenerateDdl(true);
hibernateJpaVendorAdapter.setDatabase(Database.MYSQL);
// hibernateJpaVendorAdapter.setDatabase(Database.H2);
return hibernateJpaVendorAdapter;
}
@Bean
public PlatformTransactionManager transactionManager() {
return new JpaTransactionManager();
}
}
完全なスタック トレース:

「entityManagerFactory」は [web.xml][1] で宣言されています。エラーは、そのような名前の Bean が存在しないことを示しています。しかし、[JPA config][3] ファイルに含めました。したがって、JPA javaConfig ファイル内の Bean が取得されていないと推測しています。構成がどこで失敗しているのか疑問に思っています。
