3.Spring 高级话题
4.Spring mvc基础
5.Spring Boot基础
5.1 Spring boot概述
5.1.1 什么是spring boot
使用习惯优于配置的理念.不用或者只需要很少的spring配置.
5.1.2 Spring boot核心功能
- 1.独立运行的Spring 项目
支持用jar包的形式运行. - 2.内嵌Servlet容器
内嵌Tomcat,jetty - 3.提供starter,简化maven配置.
- 4.自动配置Spring
- 5.准生产的应用监控
http,ssh,telnet对运行时的项目进行监控 - 6.无代码生产和XML配置
5.1.3 Spring boot优缺点
优点
- 1)快速构建项目
- 2)对主流开发框架的无配置集成
- 3)项目可以独立运行,无须外部依赖servlet容器
- 4)提供运行时的应用监控
- 5)机极大的提高了开发,部署效率
- 6)与云计算的天然集成.
缺点
- 1)书籍文档少
- 2)不认可spring,可能不习惯
5.1.4 关于本书Spring boot版本
Spring boot 1.3.0
5.2 Spring boot快速搭建
5.2.1 http://start.spring.io
进入该页面能协助创建spring boot项目.
5.2.2 Spring Tool Suite
工具不错.
5.2.3 Intellij IDEA
工具口碑好
5.2.4 Spring boot CLI
下载链接
查看10.2章节.
5.2.5 maven 手工构建
5.2.6 简单演示
@SpringBootApplication :开启自动配置.
通过maven命令: mvn spring-boot:run
6.Spring Boot核心
6.1 基本配置
6.1.1 入口类和@SpringBootApplicaion
@Target(ElementType.TYPE)
@Retention(RetentionPolicy.RUNTIME)
@Documented
@Inherited
@Configuration
@EnableAutoConfiguration
@ComponentScan
public @interface SpringBootApplication {
}@EnableAutoConfiguration让Spring boot根据类路径中的jar包依赖为当前项目进行自动配置.
Spring Boot启动类要放在groupId+arctifactID目录下.
6.1.2 关闭特定的自动配置
@SpringBootApplication(exclude={DateSourceAutoConfiguration.class})6.1.3 定制Banner
1) 修改banner内容
/src/main/resources目录下创建一个banner.txt文件，然后将ASCII字符画复制进去，就能替换默认的banner了.
2)属性设置.
| 属性 | 说明 |
|---|---|
| ${AnsiColor.BRIGHT_RED} | 设置控制台中输出内容的颜色 |
| ${application.version} | 用来获取MANIFEST.MF文件中的版本号 |
| ${spring-boot.version} | Spring Boot的版本号 |
application.formatted−version|格式化后的
{application.version}版本信息
3)关闭banner方法1
SpringApplication application = new SpringApplication(App.class);
/*
* Banner.Mode.OFF:关闭;
* Banner.Mode.CONSOLE:控制台输出，默认方式;
* Banner.Mode.LOG:日志输出方式;
*/
application.setBannerMode(Banner.Mode.OFF);
application.run(args); 4)关闭banner方法2
在application.proerpties进行banner的显示和关闭：
是否显示banner，可选值[true|false]
spring.main.show-banner=false6.1.4 Spring Boot的配置文件
application.properties或application.yml
//举几个例子:
server.port=9090
server.context-path=/helloboot
server:
port: 9090
contextPath:/helloboot
spring.redis.cluster.nodes[0]=192.168.0.1:6379
spring.redis.cluster.nodes[1]=192.168.0.2:6379
spring:
redis:
cluster:
nodes:
- 192.168.0.1:6379
- 192.168.0.2:6379 Spring Boot application.properties或application.yml相关配置
application.properties 改成 application.yml

启动日志附件
6.5.1 运行原理
6.1.1 中的
@SpringBootApplication中有一个核心注解为@EnableAutoConfiguration
@Target(ElementType.TYPE)
@Retention(RetentionPolicy.RUNTIME)
@Documented
@Inherited
@AutoConfigurationPackage
@Import(EnableAutoConfigurationImportSelector.class)
public @interface EnableAutoConfiguration {
/**
* Exclude specific auto-configuration classes such that they will never be applied.
* @return the classes to exclude
*/
Class<?>[] exclude() default {};
/**
* Exclude specific auto-configuration class names such that they will never be
* applied.
* @return the class names to exclude
* @since 1.3.0
*/
String[] excludeName() default {};
}而EnableAutoConfiguration的关键功能为@Import注解导入EnableAutoConfigurationImportSelector的配置功能,EnableAutoConfigurationImportSelector使用SpringFactoriesLoader.loadFactoryNames方法来扫描META-INF/spring.factories文件中的jar包,而spring-boot-autoconfigure-1.3.0.x.jar中就有spring.factories.
//摘取核心代码
package org.springframework.core.io.support
public abstract class SpringFactoriesLoader {
public static final String FACTORIES_RESOURCE_LOCATION = "META-INF/spring.factories";
public static List<String> loadFactoryNames(Class<?> factoryClass, ClassLoader classLoader) {
String factoryClassName = factoryClass.getName();
try {
Enumeration<URL> urls = (classLoader != null ? classLoader.getResources(FACTORIES_RESOURCE_LOCATION) :
ClassLoader.getSystemResources(FACTORIES_RESOURCE_LOCATION));
List<String> result = new ArrayList<String>();
while (urls.hasMoreElements()) {
URL url = urls.nextElement();
Properties properties = PropertiesLoaderUtils.loadProperties(new UrlResource(url));
String factoryClassNames = properties.getProperty(factoryClassName);
result.addAll(Arrays.asList(StringUtils.commaDelimitedListToStringArray(factoryClassNames)));
}
return result;
}
catch (IOException ex) {
throw new IllegalArgumentException("Unable to load [" + factoryClass.getName() +

6.5.2 核心注解
打开spring.factories中的任意一个AutoConfiguration文件,一般都有下面的条件注解,在spring-boot-autoconfigure-1.3.0.x.jar的org.springframework.boot.autoconfigure.condition包下,条件注解如下.
| 名称 | 说明 | 备注 |
|---|---|---|
| @ConditionalOnBean | 当容器里存在指定的Bean的条件下 | |
| @ConditionalOnClass | 当前类路径下存在指定的类的条件下 | |
| @ConditionalOnExpression | 基于SpEL表达式作为判断条件 | |
| @ConditionalOnJava | 基于JVM版本作为判断条件 | |
| @ConditionalOnJndi | 在JNDI存在的条件下查找指定的位置 | |
| @ConditionalOnMissingBean | 当容器里没有指定的Bean的条件下 | |
| @ConditionalOnMissingClass | ConditionalOnMissingClass | |
| @ConditionalOnNotWebApplication | 当前项目不是web项目的条件下 | |
| @ConditionalOnProperty | 指定的属性是否有指定的值的条件下 | |
| @ConditionalOnResource | 类路径下是否有指定的值 | |
| @ConditionalOnSingleCandidate | 指定Bean在容器中只有一个，或者虽然有多个但是指定首选的Bean | |
| @ConditionalOnWebApplication | 当前项目是Web项目的条件下 |
ConditionalOnWebApplication 源码如下:
@Target({ ElementType.TYPE, ElementType.METHOD })
@Retention(RetentionPolicy.RUNTIME)
@Documented
@Conditional(OnWebApplicationCondition.class)
public @interface ConditionalOnWebApplication {
}其中@Conditional是OnWebApplicationCondition.class
OnWebApplicationCondition源码如下
@Order(Ordered.HIGHEST_PRECEDENCE + 20)
class OnWebApplicationCondition extends SpringBootCondition {
private static final String WEB_CONTEXT_CLASS = "org.springframework.web.context."
+ "support.GenericWebApplicationContext";
@Override
public ConditionOutcome getMatchOutcome(ConditionContext context,
AnnotatedTypeMetadata metadata) {
boolean webApplicationRequired = metadata
.isAnnotated(ConditionalOnWebApplication.class.getName());
ConditionOutcome webApplication = isWebApplication(context, metadata);
if (webApplicationRequired && !webApplication.isMatch()) {
return ConditionOutcome.noMatch(webApplication.getMessage());
}
if (!webApplicationRequired && webApplication.isMatch()) {
return ConditionOutcome.noMatch(webApplication.getMessage());
}
return ConditionOutcome.match(webApplication.getMessage());
}
private ConditionOutcome isWebApplication(ConditionContext context,
AnnotatedTypeMetadata metadata) {
if (!ClassUtils.isPresent(WEB_CONTEXT_CLASS, context.getClassLoader())) {
return ConditionOutcome.noMatch("web application classes not found");
}
if (context.getBeanFactory() != null) {
String[] scopes = context.getBeanFactory().getRegisteredScopeNames();
if (ObjectUtils.containsElement(scopes, "session")) {
return ConditionOutcome.match("found web application 'session' scope");
}
}
if (context.getEnvironment() instanceof StandardServletEnvironment) {
return ConditionOutcome
.match("found web application StandardServletEnvironment");
}
if (context.getResourceLoader() instanceof WebApplicationContext) {
return ConditionOutcome.match("found web application WebApplicationContext");
}
return ConditionOutcome.noMatch("not a web application");
}
}有方法isWebApplication和getMatchOutcome.
isWebApplication是判断是否为webApplication.
getMatchOutcome 实现是abstract class SpringBootCondition的getMatchOutcome.
matches是实现了接口Condition的boolean matches,
SpringBootCondition中matches有调用了自身的getMatchOutcome方法.
捋捋核心原理1-关于Condition:
1.顶级接口 public interface Condition,方法matches
2.抽象类 abstract class SpringBootCondition,实现matches,同时调用自己的抽象方法 getMatchOutcome
3.具体类 class OnWebApplicationCondition extends SpringBootCondition,继承的同时重写getMatchOutcome,里面有判断.最终实现了被顶级接口matches是实现了接口Condition的boolean的matches判断现象..
class OnWebApplicationCondition extends SpringBootCondition{}
//摘选部分代码
public abstract class SpringBootCondition implements Condition {
@Override
public final boolean matches(ConditionContext context,
AnnotatedTypeMetadata metadata) {
String classOrMethodName = getClassOrMethodName(metadata);
try {
ConditionOutcome outcome = getMatchOutcome(context, metadata);
logOutcome(classOrMethodName, outcome);
recordEvaluation(context, classOrMethodName, outcome);
return outcome.isMatch();
}
catch (NoClassDefFoundError ex) {
throw new IllegalStateException("Could not evaluate condition on "
+ classOrMethodName + " due to internal class not found. "
+ "This can happen if you are @ComponentScanning a "
+ "springframework package (e.g. if you put a @ComponentScan "
+ "in the default package by mistake)", ex);
}
catch (RuntimeException ex) {
throw new IllegalStateException(
"Error processing condition on " + getName(metadata), ex);
}
}
public abstract ConditionOutcome getMatchOutcome(ConditionContext context,
AnnotatedTypeMetadata metadata);
}
public interface Condition {
/**
* Determine if the condition matches.
* @param context the condition context
* @param metadata metadata of the {@link org.springframework.core.type.AnnotationMetadata class}
* or {@link org.springframework.core.type.MethodMetadata method} being checked.
* @return {@code true} if the condition matches and the component can be registered
* or {@code false} to veto registration.
*/
boolean matches(ConditionContext context, AnnotatedTypeMetadata metadata);
}
Spring Boot自动配置详解(有例子),自己模拟写一个
6.5.3 实例分析
分析一个简单的SpringBoot内置的自动配置功能:http编码配置.
@ConfigurationProperties(prefix = "spring.http.encoding")//application.properties和配置的前缀是spring.http.encoding
public class HttpEncodingProperties {
//默认配置UTF-8,如果要修改用配置 spring.http.encoding.Charset=GBK
public static final Charset DEFAULT_CHARSET = Charset.forName("UTF-8"); //默认配置是UTF-8
/**
* Charset of HTTP requests and responses. Added to the "Content-Type" header if not
* set explicitly.
*/
private Charset charset = DEFAULT_CHARSET;
/**
* Force the encoding to the configured charset on HTTP requests and responses.
*/
//设置forceEncoding 默认true,如果要修改用配置 spring.http.encoding.force=false
private boolean force = true;
public Charset getCharset() {
return this.charset;
}
public void setCharset(Charset charset) {
this.charset = charset;
}
public boolean isForce() {
return this.force;
}
public void setForce(boolean force) {
this.force = force;
}
}
@Configuration
@EnableConfigurationProperties(HttpEncodingProperties.class)//对上面配置类HttpEncodingProperties.开启属性注入,通过EnableConfigurationProperties,使用@Autowired注入.
@ConditionalOnClass(CharacterEncodingFilter.class)//当CharacterEncodingFilter在类路径的条件下
//当设置spring.http.encoding=enabled的情况下,如果么有设置则默认true.
@ConditionalOnProperty(prefix = "spring.http.encoding", value = "enabled", matchIfMissing = true)
public class HttpEncodingAutoConfiguration {
@Autowired
private HttpEncodingProperties httpEncodingProperties;
@Bean//使用java配置的方式配置CharacterEncodingFilter这Bean
@ConditionalOnMissingBean(CharacterEncodingFilter.class)//当容器中没有的时候则新建这个Bean
public CharacterEncodingFilter characterEncodingFilter() {
CharacterEncodingFilter filter = new OrderedCharacterEncodingFilter();
filter.setEncoding(this.httpEncodingProperties.getCharset().name());
filter.setForceEncoding(this.httpEncodingProperties.isForce());
return filter;
}
}
捋捋核心原理2-自动配置
有配置参数属性Bean-HttpEncodingProperties.java,有使用的配置前缀名称及配置属性名称
然后有一个配置Bean-HttpEncodingAutoConfiguration.java,这个里面用到了配置参数属性类,但是里面会用到捋捋核心原理1中的各种Condition.
核心原理总理解:
@SpringBootApplication–核心注解–>@EnableAutoConfiguration—->@Import(EnableAutoConfigurationImportSelector.class)–使用–>
SpringFactoriesLoader.loadFactoryNames–方法来扫描–>META-INF/spring.factories(spring-boot-autoconfigure-1.3.0.x.jar中,记录有哪些自动配置)–关于配置,举例HttpEncoding–>参数配置HttpEncodingProperties,自动配置HttpEncodingAutoConfiguration(spring..factories有记录,被loadFactoryNames扫走)—->HttpEncodingAutoConfiguration用Condition来判断参数配置值来启用符合条件的功能.
还有一点注意理解 想查看某个自动配置有哪些配置属性,到其对应的Properties.java累中查看即可!!
比如说spring-boot-autoconfigure-1.3.0.RELEASE解压后META-INF目录下有spring.factories,里面有Redis相关的自动配置类:springorg.springframework.boot.autoconfigure.data.redis.RedisAutoConfiguration.打开该源码
//节选源码
@Configuration
@ConditionalOnClass({ JedisConnection.class, RedisOperations.class, Jedis.class })
@EnableConfigurationProperties
public class RedisAutoConfiguration {
@Bean(name = "org.springframework.autoconfigure.redis.RedisProperties")
@ConditionalOnMissingBean
public RedisProperties redisProperties() {
return new RedisProperties();
}里面提到:RedisProperties,查看就知道配置有database,host,password,port,timeout,pool等
package org.springframework.boot.autoconfigure.data.redis;
import org.springframework.boot.context.properties.ConfigurationProperties;
@ConfigurationProperties(prefix = "spring.redis")
public class RedisProperties {
/**

private int port = 6379;
/**

private int timeout;
private Pool pool;
private Sentinel sentinel;
public int getDatabase() {
return this.database;

public void setDatabase(int database) {
this.database = database;

return this.timeout;
}
public Sentinel getSentinel() {
return this.sentinel;
}
public void setSentinel(Sentinel sentinel) {
this.sentinel = sentinel;
}
public Pool getPool() {
return this.pool;
}
public void setPool(Pool pool) {
this.pool = pool;
}
/**
* Pool properties.
*/
public static class Pool {
/**
* Max number of "idle" connections in the pool. Use a negative value to indicate
* an unlimited number of idle connections.
*/
private int maxIdle = 8;
/**
* Target for the minimum number of idle connections to maintain in the pool. This
* setting only has an effect if it is positive.
*/
private int minIdle = 0;
/**
* Max number of connections that can be allocated by the pool at a given time.
* Use a negative value for no limit.
*/
private int maxActive = 8;
/**
* Maximum amount of time (in milliseconds) a connection allocation should block
* before throwing an exception when the pool is exhausted. Use a negative value
* to block indefinitely.
*/
private int maxWait = -1;
public int getMaxIdle() {
return this.maxIdle;
}
public void setMaxIdle(int maxIdle) {
this.maxIdle = maxIdle;
}
public int getMinIdle() {
return this.minIdle;
}
public void setMinIdle(int minIdle) {
this.minIdle = minIdle;
}
public int getMaxActive() {

}
public void setMaxActive(int maxActive) {
this.maxActive = maxActive;
}
public int getMaxWait() {
return this.maxWait;
}
public void setMaxWait(int maxWait) {
this.maxWait = maxWait;
}
}
/**
* Redis sentinel properties.
*/
public static class Sentinel {
/**
* Name of Redis server.
*/
private String master;
/**
* Comma-separated list of host:port pairs.
*/
private String nodes;
public String getMaster() {
return this.master;
}
public void setMaster(String master) {
this.master = master;
}
public String getNodes() {
return this.nodes;
}
public void setNodes(String nodes) {
this.nodes = nodes;
}
}
}
