spring - PropertySource 无法转换 bool 值

Question

我有一个 spring 应用程序，它有一些 XML 配置，可以很好地使用 @Value 从属性文件中连接 bool 值。我正在将一个单元测试放在一起，使用@Configuration 样式为测试定义配置，@Value 注释似乎给出了非字符串类型的问题。我查看了文档并发帖，但我没有运气解决这个问题。

  private String jdbcUrl;
  @Value("${jdbc.username}")
  private String jdbcUsername;

任何帮助将不胜感激

Answer 1

我只是想改进答案。

解决方案 1:

我们可以使用 PropertySourcesPlaceholderConfigurer

注意:假设类路径中有 bean.properties 和 jdbc.properties

1) ApplicationProperties.Java

 public class ApplicationProperties {

            @Bean
            public PropertyPlaceholderConfigurer dbPropertiesConfigurer() {
                PropertyPlaceholderConfigurer configurer = new 
PropertyPlaceholderConfigurer();
                configurer.setLocations(new Resource[] 
                {new ClassPathResource("bean.properties"), 
                 new ClassPathResource("jdbc.properties")});
                configurer.setIgnoreUnresolvablePlaceholders(true);
                return configurer;
            }
        }

2)实际配置文件

@Configuration
@Import(ApplicationProperties.class)
public class Config {
  @Value("${jdbc.driver}")
  private String jdbcDriver;
  @Value("${jdbc.url}")
  private String jdbcUrl;
  @Value("${jdbc.username}")
  private String jdbcUsername;
  @Value("${jdbc.password}")
  private String jdbcPassword;

  @Value("${cc.manager.clear.decline}")
  private Boolean clearDecline;
  @Value("${cc.manager.agent.schedule.url}")
  private String agentUrl;
  @Value("${cc.manager.reporting.service.url}")
  private String reportingUrl;

<truncated..>

解决方案 2:

另一种使用属性文件值的方法是使用 Enviornment

@Configuration
@PropertySource("classpath:jdbc.properties")
public class ApplicationConfiguration {

@Inject
private Environment environment;

  @Bean
  public DataSource getDataSource() {
    BasicDataSource ds = new BasicDataSource();
    ds.setDriverClassName(environment.getProperty("driver.class.name"));
    ds.setUrl(environment.getProperty("jdbc.url"));
    ds.setUsername(environment.getProperty("username"));
    ds.setPassword(environment.getProperty("password"));

    return ds;
  }

}
