擷取SpringBoot項目骨架
使用IDE建立Spring應用選擇依賴 或 在http://start.spring.io/ 選擇web(thymeleaf會自動包含web)技術下載下傳壓縮包,解壓,導入即可。換了maven鏡像倉庫可能找不到依賴。此時就直接用第二種方法簡單
SpringBoot中的SpringMVC和Thymeleaf的使用
說明:劃掉的與本例無關。
注意:
index.html可以被localhost:8080/直接通路 同理還有public META-NF resources下的index
修改名稱就不行,這裡Springboot預設靜态首頁index.html,并且該映射不因addViewController被重寫而覆寫
把任何頁面放入templates需要使用controller跳轉。無法直接通路,預設是templates,通過TemplatResolver bean修改
此處使用SpringMVC是以用test.html,通過controller
static檔案中的預設不會被攔截,可以直接通路,一般存放js,cs

控制器和配置
說明:https配置部分可以忽略,因為要生成SSL與springmvc無關,,注釋掉即可
package com.wisely.ch7_2;
import java.util.ArrayList;
import java.util.List;
import com.wisely.ch7_2.javabean.Person;
import org.apache.catalina.Context;
import org.apache.catalina.connector.Connector;
import org.apache.tomcat.util.descriptor.web.SecurityCollection;
import org.apache.tomcat.util.descriptor.web.SecurityConstraint;
import org.springframework.boot.SpringApplication;
import org.springframework.boot.autoconfigure.SpringBootApplication;
import org.springframework.boot.context.embedded.EmbeddedServletContainerFactory;
import org.springframework.boot.context.embedded.tomcat.TomcatEmbeddedServletContainerFactory;
import org.springframework.context.annotation.Bean;
import org.springframework.http.MediaType;
import org.springframework.stereotype.Controller;
import org.springframework.ui.Model;
import org.springframework.web.bind.annotation.RequestMapping;
import org.springframework.web.bind.annotation.ResponseBody;
import org.springframework.web.servlet.config.annotation.WebMvcConfigurerAdapter;
// 這裡啟動類裡面放了控制器與配置資訊,僅僅是為了友善,希望不要效仿。
@Controller
@SpringBootApplication
public class Ch72Application extends WebMvcConfigurerAdapter {
public static void main(String[] args) {
SpringApplication.run(Ch72Application.class, args);
}
@RequestMapping("/")
public String inde(Model model) {
Person single = new Person("aa",11);
List<Person> people = new ArrayList<Person>();
Person person1 = new Person("張三",11);
Person person2 = new Person("李四",22);
Person person3 = new Person("王五",33);
people.add(person1);
people.add(person2);
people.add(person3);
model.addAttribute("singlePerson",single);
model.addAttribute("people",people);
return "test";
}
/**
* 特點的伺服器配置,tomcat
*
* @return
*/
@Bean
public EmbeddedServletContainerFactory servletContainer() {
TomcatEmbeddedServletContainerFactory tomcat = new TomcatEmbeddedServletContainerFactory() {
/**
* 重寫postProcessContext方法
*/
@Override
protected void postProcessContext(Context context) {
SecurityConstraint securityConstraint = new SecurityConstraint();
securityConstraint.setUserConstraint("CONFINDENTIAL");
SecurityCollection collection = new SecurityCollection();
collection.addPattern("/*");
securityConstraint.addCollection(collection);
context.addConstraint(securityConstraint);
}
};
// 添加tomcat的connector
tomcat.addAdditionalTomcatConnectors(httpConnector());
return tomcat;
}
/**
* 将http強制重定向至https
*
* @return
*/
@Bean
public Connector httpConnector() {
Connector connector = new Connector(
"org.apache.coyote.http11.Http11NioProtocol");
connector.setScheme("http");
connector.setPort(8080);
connector.setSecure(false);
connector.setRedirectPort(8443);// 重定向端口 https
return connector;
}
}
注意:
如果需要更改預設的視圖引擎 伺服器,需要繼承WebMvcConfigurerAdapter。如果需要完全控制MVC的配置,則在@Configuration注解的類上加@EnableWebMvc。這裡thymeleaf是使用預設的自動配置
application.properies配置
說明:主要是SSL配置,還沒有學到或者看不懂可以忽略,不影響使用Thyemeleaf。使用https,則無論輸入http://localhost:8080還是https://localhost:8443都可以通路,前者被強轉定向到https.
內建Thymeleaf3.0
如果報錯标簽沒有閉合可以添加屬性配置或者使用thymeleaf3.0【添加pom的紅色部分】
<properties>
<thymeleaf.version>3.0.0.RELEASE</thymeleaf.version>
<thymeleaf-layout-dialect.version>2.0.0</thymeleaf-layout-dialect.version>
<project.build.sourceEncoding>UTF-8</project.build.sourceEncoding>
<project.reporting.outputEncoding>UTF-8</project.reporting.outputEncoding>
<java.version>1.7</java.version>
</properties>
當然也可以繼續使用Thymeleaf2.x,但是需要配置
#解析非嚴格的html5
spring.thymeleaf.mode=LEGACYHTML5
并增加依賴
<dependency>
<groupId>net.sourceforge.nekohtml</groupId>
<artifactId>nekohtml</artifactId>
<version>1.9.22</version>
</dependency>
#以下都是預設配置
#server.port=80
##機關是秒,預設是30分鐘
#server.session-timeout=30*60
#通路路徑
#server.context-path=/
#tomcat編碼
#server.tomcat.uri-encoding=utf-8
#是否開啟tomcat壓縮
#server.tomcat.compression=off
server.port = 8443
下面都是https配置,上面沒有配置,則下面不需要加上
server.ssl.key-store = .keystore https證書的檔案 classpath下
server.ssl.key-store-password = https證書密碼
server.ssl.keyStoreType = JKS 密鑰類型
server.ssl.keyAlias: tomcat 證書别名
調試/啟動項目
SPringBoot可以使用maven啟動 或者以普通java程式啟動 【tomcat當然可以】
可以添加debug=true 檢視自動配置的相信資訊。
觀察控制台自動配置資訊
@SpringBootApplication相當與組合了 自動配置注解與自動掃描注解
即@SpringBootApplication注解等價于以預設屬性使用@Configuration,@EnableAutoConfiguration和@ComponentScan:
控制台列印出許多自動配置的資訊均是由組合注解@SpringBootApplication來完成 。
通路https://localhost:8443/ 【沒有配置https的8080】
下面這個紅色應該是浏覽器問題。不影響。
