spring-boot-starter-jdbc DAO存储库对象未注入到工作的遗留webservice中

Question

    package X;
    ....
    @Component
    @WebService(name = "***",***)
    @BindingType("http://schemas.xmlsoap.org/wsdl/soap/http")
    @XmlSeeAlso({
        packagesxxx.class,
        ....
        })
    public class BServiceManager
        implements xxxxx
        {
         ....
         @Autowired    
         private ItemRepository irepo;
         
         ....
         @WebMethod(**)
         @WebResult(***)
         public ResponseDataInfo sendInfo( ){
         ....
         trepo.saveitem(item)
         ....         
         }
    }

    package Y.Z;
    import org.springframework.beans.factory.annotation.Autowired;
    import org.springframework.jdbc.core.JdbcTemplate;
    import org.springframework.dao.DataAccessException;
    import org.springframework.stereotype.Component;
    import org.springframework.stereotype.Repository;

    @Component
    @Repository
    public class ItemRepository {
    
        @Autowired
        private JdbcTemplate jdbcTemplate ;
        
        ....
        public boolean saveitem(Item item) {
        
        ....
        }
    
    
     }

    package Y.Z;
    public class Item {
        ....
    }

    package Y;

    import org.springframework.boot.SpringApplication;
    import org.springframework.boot.autoconfigure.SpringBootApplication;
    import org.springframework.context.annotation.ComponentScan;
    
    //@ComponentScan(basePackages={"Y","Y.Z","X"})
    @SpringBootApplication
    public class GetItemsApplication   {
        ....
        public static void main(String[] args) {
            SpringApplication.run(GetItemsApplication.class, args);
            log.info("--Spring Boot inits done--");
        }
        
    }

Application.Properties

    spring.data.jpa.repositories.enabled=false
    spring.data.jdbc.repositories.enabled=true

    # MySQL properties
    spring.datasource.url=****
    spring.datasource.username=****
    spring.datasource.password=****
    ....
    spring.datasource.driver-class-name=com.mysql.jdbc.Driver
    logging.level.org.springframework.jdbc.core.JdbcTemplate=debug

注意：即使有数据源bean也没有帮助：

    File: DataSourceConfig.java

    package Y.Z;
    import javax.sql.DataSource;
    import org.springframework.beans.factory.annotation.Qualifier;
    import org.springframework.boot.autoconfigure.jdbc.DataSourceBuilder;
    import org.springframework.context.annotation.Bean;
    import org.springframework.context.annotation.Configuration;
    import org.springframework.jdbc.core.JdbcTemplate;
    //@EnableJdbcRepositories for Spring

    @Configuration
    public class MDataSourceConfig {
        
        @Bean
        public DataSource dataSource() {
            DataSourceBuilder dataSourceBuilder = DataSourceBuilder.create();
            return dataSourceBuilder.build();      
        }

        @Bean
        public JdbcTemplate getJdbcTemplate() {
           return new JdbcTemplate(dataSource());
        }            
    }

您的Webservice似乎不是由Spring创建的。因此Spring无法控制其依赖项，因此必须通过编程方式获取依赖项。

有很多方法可以做到这一点。

• 简单但不是很优雅，使用的全局变量可能会导致问题，尤其是在测试中:https://stackoverflow.com/a/18486178/66686
• 更优雅，但需要使用@configurable
