1.@NotEmpty注解廢棄
spring-boot-starter-web依賴中中包含了hibernate-validator
image.png
使用org.hibernate.validator.constraints.NotEmpty時(shí)發(fā)現(xiàn)已經(jīng)廢棄
對(duì)應(yīng)的文檔說(shuō)明http://docs.jboss.org/hibernate/validator/6.0/api/index.html?org/hibernate/validator/constraints/NotEmpty.html
需要改用javax.validation.constraints.NotEmpty
源碼對(duì)比

2.java.net.URLEncoder中encode(String s)方法過(guò)期
廢棄的原因是字符串可能因平臺(tái)默認(rèn)編碼不同而不同
需要改用encode(String s, String enc)
s：要轉(zhuǎn)換的 String
enc：所支持的字符編碼名稱
源碼對(duì)比
encode(String s)方法源碼，deprecated中官方說(shuō)明了廢棄原因
/**
* @deprecated The resulting string may vary depending on the platform's
* default encoding. Instead, use the encode(String,String)
* method to specify the encoding.
*/
@Deprecated
public static String encode(String s) {
String str = null;
try {
str = encode(s, dfltEncName);
} catch (UnsupportedEncodingException e) {

}
return str;
}
encode(String s, String enc)方法源碼

StringBuffer out = new StringBuffer(s.length());
Charset charset;
CharArrayWriter charArrayWriter = new CharArrayWriter();

3.配置類WebMvcConfigurerAdapter過(guò)期
WebMvcConfigurerAdapter配置類其實(shí)是Spring內(nèi)部的一種配置方式，采用JavaBean的形式來(lái)代替?zhèn)鹘y(tǒng)的xml配置文件形式進(jìn)行針對(duì)框架個(gè)性化定制
SpringBoot2.X,Spring 5.0 以后WebMvcConfigurerAdapter會(huì)取消掉
替代方法：實(shí)現(xiàn)WebMvcConfigurer接口

public class InterceptorConfig implements WebMvcConfigurer {
@Override
public void addInterceptors(InterceptorRegistry registry) {
registry.addInterceptor(authenticationInterceptor())
.addPathPatterns("/**");
