18. Dubbo RPC 服务
一、 Web servlet、listener、interceptor等
1. servlet：
启动类添加注解@ServletComponentScan
编写servlet：
@WebServlet("/web")
public class BootSevlet implements Servlet {
...
2. Interceptor:
编写：
/**
* BootInterceptor
*/
public class BootInterceptor implements HandlerInterceptor {
...
注册：WebMvcConfigurerAdapter->addInterceptor方法。
@Configuration
public class ApplicationConfig {
@Configuration
public class WebMvcConfigurer extends WebMvcConfigurerAdapter {
public void addInterceptors(InterceptorRegistry registry) {
registry.addInterceptor(new BootInterceptor()).addPathPatterns("/**");
super.addInterceptors(registry);
}
...
3. listenenr：实现各种listener
@WebListener
public class BootListener implements ServletContextListener {
...
二、mybatis配置集成，多数据源配置
配置文件：
1. 接口方式开发dao，扫描包配置 ：@MapperScan(basePackages = "org.windwant.spring.mapper")
2. 配置dataSource，sqlSessionFactory
datasource 根据application.yml配置的数据源配置
application.yml
datasource:
local:
url: $[datasource.local.url]
username: $[datasource.local.user]
password: $[datasource.local.password]
driverClassName: com.mysql.jdbc.Driver
type: org.apache.commons.dbcp.BasicDataSource
max-active: 30
max-idle: 10
max-wait: 10
test-while-idle: true
remote:
url: $[datasource.remote.url]
username: $[datasource.remote.user]
password: $[datasource.remote.password]
driverClassName: com.mysql.jdbc.Driver
type: org.apache.commons.dbcp.BasicDataSource
max-active: 30
max-idle: 10
max-wait: 10
test-while-idle: true
DataSource 注解配置：
/**
* Created by windwant on 2016/12/30.
* implements EnvironmentAware, ApplicationContextAware
*/
@Configuration
public class MybatisConfig {
// private Environment environment;
//
// @Override
// public void setEnvironment(Environment environment) {
// this.environment = environment;
// }
@Primary
@Bean(name = "localDataSource")
@Order(value = 1)
@ConfigurationProperties(prefix = "datasource.local")
public DataSource localDataSource(){
return DataSourceBuilder.create().build();
}
@Order(value = 2)
@Bean(name = "remoteDataSource")
@ConfigurationProperties(prefix = "datasource.remote")
public DataSource remoteDataSource() {
return DataSourceBuilder.create().build();
}
@Bean(name = "routingDataSource")
@Order(value = 3)
public DataSource routingDataSource(@Qualifier("localDataSource") DataSource localDataSource,
@Qualifier("remoteDataSource") BasicDataSource remoteDataSource){
RoutingDataSource routingDataSource = new RoutingDataSource();
Map<Object, Object> dataSources = new HashMap<>();
dataSources.put(Type.LOCAL.name(), localDataSource);
dataSources.put(Type.REMOTE.name(), remoteDataSource);
routingDataSource.setTargetDataSources(dataSources);
routingDataSource.setDefaultTargetDataSource(localDataSource);
return routingDataSource;
}
@Bean
@Order(value = 4)
@Lazy
public SqlSessionFactory sqlSessionFactory(@Qualifier("remoteDataSource") DataSource remoteDataSource,
@Qualifier("localDataSource") DataSource localDataSource,
@Qualifier("routingDataSource") DataSource routingDataSource) throws Exception {
SqlSessionFactoryBean factoryBean = new SqlSessionFactoryBean();
factoryBean.setDataSource(routingDataSource);
factoryBean.getObject().getConfiguration().setMapUnderscoreToCamelCase(true);
factoryBean.setMapperLocations(new PathMatchingResourcePatternResolver().getResources("classpath*:mybatis/*.xml"));
factoryBean.afterPropertiesSet();
return factoryBean.getObject();
}
// private ApplicationContext ctx;
//
// @Override
// public void setApplicationContext(ApplicationContext applicationContext) throws BeansException {
// this.ctx = applicationContext;
// }
}
项目添加Bean配置：
@Bean
public MapperScannerConfigurer mapperScannerConfigurer() {
MapperScannerConfigurerProxy mapperScannerConfigurerProxy = new MapperScannerConfigurerProxy();
mapperScannerConfigurerProxy.setBasePackage("org.windwant.spring.mapper");
return mapperScannerConfigurerProxy;
}
三、集成jmx监控 MBean
/**
* Created by windwant on 2017/4/6.
* JMX Mbean 监控 可以通过jconsole进行mbean暴露操作
*/
@Component
@ManagedResource(description = "sboot svr")
public class WAMBean {
// 属性
private String name;
private int age;
private String message;
@ManagedAttribute
public String getName() {
System.out.println("name: " + name);
return name;
}
@ManagedAttribute
public void setName(String name) {
this.name = name;
}
@ManagedAttribute
public int getAge() {
System.out.println("age: "+age);
return age;
}
@ManagedAttribute
public void setAge(int age) {
this.age = age;
}
@ManagedAttribute
public String getMessage() {
System.out.println("message: " + message);
return message;
}
@ManagedAttribute
public void setMessage(String message) {
this.message = message;
}
@ManagedOperation
@ManagedOperationParameter(name = "message", description = "message")
public void call(String message) {
System.out.println("call：" + message);
}
@ManagedOperation
@ManagedOperationParameter(name = "who", description = "who")
@ManagedOperationParameter(name = "what", description = "what")
public void look(String who, String what){
System.out.println(who + " 发现了 " + what);
}
@Autowired
FTPTransport ftpTransport;
@ManagedOperation
public void upload() throws FileNotFoundException {
FileInputStream f = null;
try {
f = new FileInputStream(new File("D:\\a.json"));
ftpTransport.uploadFile("ajson", f);
}catch (Exception e){
e.printStackTrace();
}finally {
try {
if(f != null){
f.close();
}
}catch (Exception e){
e.printStackTrace();
}
}
System.out.println("to play....");
}
}
四：定时任务配置 Scheduled
@Component
public class BootJob {
private static final SimpleDateFormat dateFormat = new SimpleDateFormat("HH:mm:ss");
@Scheduled(fixedRate = 1000)
public void reportTime(){
System.out.println("current time is: " + dateFormat.format(new Date()));
}
}
五：参数验证
参数Bean：验证注解 @NotBlank @NotNull等
public class Guest {
@NotBlank(message = "{guest.name}")
private String name;
private Integer sex;
Controller：参数添加@Valid注解
@RequestMapping("/hellox")
Map<String, Object> hellox(@Valid Guest guest, BindingResult result){
if(result.hasErrors()){
return Response.response(-1, Constants.FAILED, result.getAllErrors());
}
使用lang验证提示信息：
@Bean
public LocalValidatorFactoryBean localValidatorFactoryBean(){
LocalValidatorFactoryBean localValidatorFactoryBean = new LocalValidatorFactoryBean();
localValidatorFactoryBean.setProviderClass(HibernateValidator.class);
ReloadableResourceBundleMessageSource rrbms = new ReloadableResourceBundleMessageSource();
rrbms.setBasename("classpath:/lang/messages");
rrbms.setUseCodeAsDefaultMessage(false);
rrbms.setDefaultEncoding("UTF-8");
localValidatorFactoryBean.setValidationMessageSource(rrbms);
return localValidatorFactoryBean;
}
六：跨域处理 Cors
配置WebMvcConfigureAdapter addCorsMappings
addMapping：请求拦截
allowedOrigins：拦截请求源
allowedMethods：拦截方法
@Configuration
public class WebMvcConfigurer extends WebMvcConfigurerAdapter {
public void addInterceptors(InterceptorRegistry registry) {
registry.addInterceptor(new BootInterceptor()).addPathPatterns("/**");
super.addInterceptors(registry);
}
/**
* 跨域处理 映射所有路径 允许所有来源 以下方法请求
* @param registry
*/
@Override
public void addCorsMappings(CorsRegistry registry) {
registry.addMapping("/**")
.allowedOrigins("*")
.allowedMethods("GET", "POST", "PUT", "OPTIONS", "DELETE", "PATCH");
}
七：shiro权限配置
@Configuration
public class ShiroConfig implements EnvironmentAware {
private final static int REMEMBER_ME_MAX_AGE = 365 * 24 * 3600;
// 这是个DestructionAwareBeanPostProcessor的子类，负责org.apache.shiro.util.Initializable类型bean的生命周期的，
// 初始化和销毁。主要是AuthorizingRealm类的子类，以及EhCacheManager类
@Bean(name = "lifecycleBeanPostProcessor")
public LifecycleBeanPostProcessor lifecycleBeanPostProcessor() {
return new LifecycleBeanPostProcessor();
}
@Bean
public SimpleCookie rememberMeCookie(){
SimpleCookie simpleCookie = new SimpleCookie("rememberMe");
simpleCookie.setMaxAge(REMEMBER_ME_MAX_AGE);
return simpleCookie;
}
@Bean
public CookieRememberMeManager rememberMeManager(){
CookieRememberMeManager cookieRememberMeManager = new CookieRememberMeManager();
cookieRememberMeManager.setCookie(rememberMeCookie());
//rememberMe cookie加密的密钥 建议每个项目都不一样 默认AES算法 密钥长度(128 256 512 位)
cookieRememberMeManager.setCipherKey(Base64.decode("2AvVhdsgUs0FSA3SDFAdag=="));
return cookieRememberMeManager;
}
// 为了对密码进行编码的，防止密码在数据库里明码保存，当然在登陆认证，这个类也负责对form里输入的密码进行编码。
@Bean(name = "hashedCredentialsMatcher")
public HashedCredentialsMatcher hashedCredentialsMatcher() {
HashedCredentialsMatcher credentialsMatcher = new ComHashedCredentialsMatcher();
credentialsMatcher.setHashAlgorithmName("MD5");//散列算法:这里使用MD5算法;
credentialsMatcher.setHashIterations(1);//散列的次数，比如散列两次，相当于 md5(md5(""));
credentialsMatcher.setStoredCredentialsHexEncoded(true);//true时密码加密用的是Hex编码；false时用Base64编码
return credentialsMatcher;
}
// 增加缓存减少对数据库的查询压力
@Bean(name = "ehcacheManager")
public EhCacheManager getEhCacheManager() {
EhCacheManager em = new EhCacheManager();
em.setCacheManagerConfigFile("classpath:ehcache-shiro.xml");
return em;
}
// 自定义的认证类，继承自AuthorizingRealm，负责用户的认证和权限的处理
@Bean(name = "shiroRealm")
public MyAuthorizingRealm shiroRealm() {
MyAuthorizingRealm realm = new MyAuthorizingRealm();
realm.setCredentialsMatcher(hashedCredentialsMatcher());
realm.setCachingEnabled(true);
realm.setCacheManager(getEhCacheManager());
return realm;
}
//权限管理，这个类组合了登陆，登出，权限，session的处理
@Bean(name = "securityManager")
public DefaultWebSecurityManager securityManager(){
DefaultWebSecurityManager securityManager = new DefaultWebSecurityManager();
securityManager.setRealm(shiroRealm());
securityManager.setCacheManager(getEhCacheManager());
securityManager.setRememberMeManager(rememberMeManager());
DefaultWebSessionManager defaultWebSessionManager = new DefaultWebSessionManager();
defaultWebSessionManager.setGlobalSessionTimeout(Long.parseLong(environment.getProperty("session.timeout")));
securityManager.setSessionManager(defaultWebSessionManager);
return securityManager;
}
// 开启Shiro的注解(如@RequiresRoles,@RequiresPermissions),需借助SpringAOP扫描使用Shiro注解的类,并在必要时进行安全逻辑验证 * 配置以下
// 两个bean(DefaultAdvisorAutoProxyCreator(可选)和AuthorizationAttributeSourceAdvisor)即可实现此功能
@Bean(name = "advisorAutoProxyCreator")
@DependsOn({"lifecycleBeanPostProcessor"})
public DefaultAdvisorAutoProxyCreator advisorAutoProxyCreator(){
DefaultAdvisorAutoProxyCreator advisorAutoProxyCreator = new DefaultAdvisorAutoProxyCreator();
advisorAutoProxyCreator.setProxyTargetClass(true);
return advisorAutoProxyCreator;
}
@Bean(name = "authorizationAttributeSourceAdvisor")
public AuthorizationAttributeSourceAdvisor authorizationAttributeSourceAdvisor(){
AuthorizationAttributeSourceAdvisor authorizationAttributeSourceAdvisor = new AuthorizationAttributeSourceAdvisor();
authorizationAttributeSourceAdvisor.setSecurityManager(securityManager());
return authorizationAttributeSourceAdvisor;
}
@Bean(name = "shiroFilter")
public ShiroFilterFactoryBean shiroFilterFactoryBean() {
ShiroFilterFactoryBean shiroFilterFactoryBean = new ShiroFilterFactoryBean();
shiroFilterFactoryBean.getFilters().put("comauth", new ComAuthFilter());
shiroFilterFactoryBean.setSecurityManager(securityManager());
shiroFilterFactoryBean.setLoginUrl("/");
shiroFilterFactoryBean.setSuccessUrl("/index");
shiroFilterFactoryBean.setUnauthorizedUrl("/notlogin");
Map<String, String> filterChainDefinitionMap = new LinkedHashMap<String, String>();
filterChainDefinitionMap.put("/", "user");
filterChainDefinitionMap.put("/css/**", "anon");
filterChainDefinitionMap.put("/js/**", "anon");
filterChainDefinitionMap.put("/img/**", "anon");
filterChainDefinitionMap.put("/", "anon");
filterChainDefinitionMap.put("/**.html", "anon");
filterChainDefinitionMap.put("/login", "anon");

filterChainDefinitionMap.put("/spiCalc", "anon");
filterChainDefinitionMap.put("/hello/**", "anon"); //配置不控制权限请求 anon
filterChainDefinitionMap.put("/hellox", "anon");
filterChainDefinitionMap.put("/", "anon");
filterChainDefinitionMap.put("/**", "comauth");
shiroFilterFactoryBean.setFilterChainDefinitionMap(filterChainDefinitionMap);
return shiroFilterFactoryBean;
}
private Environment environment;
@Override
public void setEnvironment(Environment environment) {
this.environment = environment;
}
}
八、Consul服务注册与发现
/**
* consul agent -server -bootstrap-expect=1 -data-dir=data -node=server0 -bind=127.0.0.1 -client 0.0.0.0 -ui

keyValueClient = consul.keyValueClient();
healthClient = consul.healthClient();
agentClient = consul.agentClient();
//注册本服务到consul
registerService(bootService, bootService, bootService, consulHost, port, 5);

}
九、reids分布式锁
public class JedisUtils {
private static final Logger logger = LoggerFactory.getLogger(JedisUtils.class);
//设置锁的lua脚本
private static final String SETNX_EXPIRE_SCRIPT = "if redis.call('setnx', KEYS[1], KEYS[2]) == 1 then\n"

}
十、SPI机制
参考：Java SPI机制
十一、static资源
配置个性化资源路径：
@Configuration
public class WebMvcConfigurer extends WebMvcConfigurerAdapter {
