spring – PropertySource无法转换布尔值
作者：互联网
我有一个Spring应用程序,它有一些XML配置,使用@Value来连接属性文件的布尔值.我正在进行单元测试,使用@Configuration样式定义测试配置,@Value注释给出非字符串类型的问题.我查看了文档并发帖,但我没有运气排序.

任何帮助将不胜感激
解决方法:
我只是想改善答案.
解决方案1：
我们可以使用PropertySourcesPlaceholderConfigurer
注意：假设您在类路径中有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：
使用属性文件值的另一种方法是使用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;
}
}
