springboot
覆盖默认版本
<properties>
<spring-data-releasetrain.version>Fowler-SR2</spring-data-releasetrain.version>
</properties>
***************************************
@ContextConfiguration(locations = { "classpath*:/applicationContext.xml" })
从属性文件中自动装配该类中
@ConfigurationProperties(prefix = "spring.redis") public class RedisProperties { /** * Database index used by the connection factory. */ private int database = 0; /** * Redis url, which will overrule host, port and password if set. */ private String url; /** * Redis server host. */ private String host = "localhost"; /** * Login password of the redis server. */ private String password; /** * Redis server port. */ private int port = 6379; // 其它参数略 }
1 Application 会扫描同级包和下级包
不过想自动配置第三方的插件
@SpringBootApplication(exclude={RedisAutoConfiguration.class,})
@PropertySource(value={"classpath:jdbc.properties",""})
@PropertySource(value = "classpath:jdbc.properties",ignoreResourceNotFound = true)
一、@PropertySource 加载外面资源文件
@PropertySource(value={"person.properties"})
@Configuration
public class SpringConfigProperty {
@Bean
public Person person(){
return new Person();
}
xml 加载外部资源方式
<context:property-placeholder location="classpath:spring-common.xml"/>
二、@value 赋值的使用
//使用@Value赋值；
//1、基本数值
//2、可以写SpEL； #{}
//3、可以写${}；取出配置文件【properties】中的值（在运行环境变量里面的值）
@Value("1")
private Integer id;
@Value("${person.nickName}")
private String name;
@Value("#{20-2}")
private String age;

如果只是静态HTML页面，不带错误信息的，在resources/public/下面创建error目录，在error目录下面创建对应的状态码html即可 ，例如，要将404映射到静态HTML文件，您的文件夹结构如下所示：
如果是动态模板页面，可以带上错误信息，在resources/templates/下面创建error目录，在error目录下面命名即可:
如果同时存在静态页面500.html和动态模板的500.html，则后者覆盖前者。即templates/error/这个的优先级比resources/public/error高。
