查询所有用户
查询id为1的用户
创建一个用户
更新id为1的用户

(参考博客:http://412887952-qq-com.iteye.com/blog/2312274)
创建messages.properties(messages_zh_CN.properties,messages_en_US.properties)文件 thymeleaf里使用#{key}显示,例如:<p th:text="#{welcome}"></p>
#指定message的basename,多个以逗号分隔,如果不加包名的话,默认从classpath路径开始,默认: messages spring.messages.basename=i18n/messages #设定加载的资源文件缓存失效时间,-1的话为永不过期,默认为-1 spring.messages.cache-seconds=3600 #设定Message bundles的编码,默认: UTF-8 #spring.messages.encoding=UTF-8
验证:火狐地址栏里输入about:config回车,搜索accept_languages,改成en_US,en
Locale locale = LocaleContextHolder.getLocale();
(或者Locale locale = RequestContextUtils.getLocale(request);)
String msg = messageSource.getMessage("welcome", null,locale);
区域解析器 默认:AcceptHeaderLocaleResolver 根据HTTP请求的头部信息accept-language来解析区域
会话区域解析器:SessionLocaleResolver
@Bean
public LocaleResolver localeResolver() {
SessionLocaleResolver slr = new SessionLocaleResolver();
//设置默认区域
slr.setDefaultLocale(Locale.CHINA);
return slr;
}
request.getSession().setAttribute(SessionLocaleResolver.LOCALE_SESSION_ATTRIBUTE_NAME, new Locale("en", "US"))
@Bean
public LocaleResolver localeResolver() {
CookieLocaleResolver slr = new CookieLocaleResolver();
//设置默认区域
slr.setDefaultLocale(Locale.CHINA);
slr.setCookieMaxAge(3600);//设置cookie有效期.
returnslr;
}
@Bean
public LocaleResolver localeResolver() {
FixedLocaleResolver slr = new FixedLocaleResolver ();
//设置默认区域
slr.setDefaultLocale(Locale.US);
returnslr;
}
@Bean
public LocaleChangeInterceptor localeChangeInterceptor() {
LocaleChangeInterceptor lci = new LocaleChangeInterceptor();
// 设置请求地址的参数,默认为:locale
// lci.setParamName(LocaleChangeInterceptor.DEFAULT_PARAM_NAME);
return lci;
}
@Override
public void addInterceptors(InterceptorRegistry registry) {
registry.addInterceptor(localeChangeInterceptor());
}
注意这个是可以和会话区域解析器以及Cookie区域解析器一起使用的, 但是不能和FixedLocaleResolver一起使用,否则会抛出异常信息。
验证:
(参考:http://blog.didispace.com/springbootaoplog/)
<dependency>
<groupId>org.springframework.boot</groupId>
<artifactId>spring-boot-starter-aop</artifactId>
</dependency>
实现AOP的切面主要有以下几个要素:
@Aspect
@Component
@Order(1)
public class WebLogAspect {
private Logger logger = Logger.getLogger(WebLogAspect.class);
ThreadLocal<Long> startTime = new ThreadLocal<>();
@Pointcut("execution(public * com.example.demo.server.controller..*.*(..))")
public void webLog(){}
@Before("webLog()")
public void doBefore(JoinPoint joinPoint) throws Throwable {
startTime.set(System.currentTimeMillis());
// 接收到请求,记录请求内容
ServletRequestAttributes attributes = (ServletRequestAttributes) RequestContextHolder.getRequestAttributes();
HttpServletRequest request = attributes.getRequest();
// 记录下请求内容
logger.info("URL : " + request.getRequestURL().toString());
logger.info("HTTP_METHOD : " + request.getMethod());
logger.info("IP : " + request.getRemoteAddr());
logger.info("CLASS_METHOD : " + joinPoint.getSignature().getDeclaringTypeName() + "." + joinPoint.getSignature().getName());
logger.info("ARGS : " + Arrays.toString(joinPoint.getArgs()));
}
@AfterReturning(returning = "ret",pointcut = "webLog()")
public void doAfterReturning(Object ret) throws Throwable {
// 处理完请求,返回内容
logger.info("RESPONSE : " + ret);
logger.info("RESPONSE : " + ret);
logger.info("SPEND TIME : " + (System.currentTimeMillis() - startTime.get()));
}
}
(参考http://www.jianshu.com/p/a9b1e2f7a749)
//这里不能用@NotBlank,因为id类型为int
private int id;
//使用groups属性来给分组命名,然后在需要的地方指定命令即可
@NotBlank(groups=NAME.class)
private String name;
@Min(1)
private Integer age;
@RestController
public class ValidateController {
@RequestMapping(value="testUser")
public void testStudent(@Validated User user) {
}
@RequestMapping(value="testUser1")
public void testStudent1(@Validated(User.NAME.class) User user) {
}
}
使用 @ScriptAssert 注解校验复杂的业务逻辑: 如果需要校验的业务逻辑比较复杂,可以使用@ScriptAssert来指定进行校验的方法, 通过方法来进行复杂业务逻辑的校验,然后返回 true或false来表明是否校验成功。
@ScriptAssert(lang="javascript",script="com.learn.validate.domain
.Student.checkParams(_this.name,_this.age,_this.classes)",
groups=CHECK.class)
public class Student {
//其他代码
/注意进行校验的方法要写成静态方法,否则会出现
//TypeError: xxx is not a function 的错误
public static boolean checkParams(String name,int age,String classes) {
if(name!=null&&age>8&classes!=null)
{
return true;
}
else
{
return false;
}
}
}
在Hibernate Validator(org.hibernate.validator.constraints)中:
@NotEmpty://CharSequence, Collection, Map 和 Array 对象不能是 null 并且相关对象的 size 大于 0。 @NotBlank://String 不是 null 且去除两端空白字符后的长度(trimmed length)大于 0。
验证:
SpringBoot+rest接口+swagger2生成API文档+validator+mybatis+aop+国际化
