之前研究了springboot整合freemarker與thymeleaf的使用。也研究了springboot發布到獨立的tomcat的使用以及使用自帶的tomcat打成jar包的使用，下面研究集成JSP之后的使用。
建議還是使用官方提倡的thymeleaf模板。而且thymeleaf與html很好的集成，便於前后端人員開發。
1.集成JSP
pom.xml添加JSP相關依賴:
<!-- 使用jsp引擎，springboot內置tomcat沒有此依賴 --> <dependency> <groupId>org.apache.tomcat.embed</groupId> <artifactId>tomcat-embed-jasper</artifactId> <scope>provided</scope> </dependency> <!-- 添加servlet依賴模塊 --> <dependency> <groupId>javax.servlet</groupId> <artifactId>javax.servlet-api</artifactId> <scope>provided</scope> </dependency> <!-- 添加jstl標簽庫依賴模塊 --> <dependency> <groupId>javax.servlet</groupId> <artifactId>jstl</artifactId> </dependency>
application.properties文件中配置相關信息:
############################################################
#
# JSP 配置
#
############################################################
spring.mvc.view.suffix=.jsp
spring.mvc.view.prefix=/WEB-INF/jsp/
注意:如果項目中集成了thymeleaf，需要關掉thymeleaf，否則會將jsp作為thymleaf解析，如下:
# 關閉緩存, 即時刷新
spring.thymeleaf.cache=false
#關閉thymeleaf引擎
spring.thymeleaf.enabled=false
對應的目錄結構:
后台Controller測試:
package cn.qlq.action; import org.springframework.stereotype.Controller; import org.springframework.ui.ModelMap; import org.springframework.web.bind.annotation.RequestMapping; @RequestMapping("JSP") @Controller public class JSPController { @RequestMapping("index") public String index(ModelMap map) { map.addAttribute("name", "testname"); return "index"; } }
訪問測試:
2.測試項目發布到獨立的tomcat運行
如果發布到獨立的tomcat運行的話，與之前的的一樣
(1)繼承SpringBootServletInitializer，重寫configure方法。
package cn.qlq.config; import org.springframework.boot.builder.SpringApplicationBuilder; import org.springframework.boot.web.support.SpringBootServletInitializer; import org.springframework.context.annotation.ComponentScan; import org.springframework.context.annotation.Configuration; // 發布到獨立的Tomcat需要繼承SpringBootServletInitializer類並重寫configure方法 @Configuration // 通過該注解來表明該類是一個Spring的配置，相當於一個xml文件 @ComponentScan(basePackages = "cn.qlq") // 配置掃描包 public class SpringConfig extends SpringBootServletInitializer { @Override protected SpringApplicationBuilder configure(SpringApplicationBuilder builder) { // 設置啟動類，用於獨立tomcat運行的入口 return builder.sources(SpringConfig.class); } }
(2)pom.xml打包的方式改為war包，將對應的jsp和servlet的包依賴改為provided即可。

(3)執行clean package打包即可
(4)將打的war包拷貝到tomcat的webapps目錄下運行即可
(5)查看tomcat啟動解壓后的目錄結構:(與之前研究的一樣，加了springboot的東西,而且provided依賴的jar包也會打到一個目錄中)
3.打成war包運行並以java -jar的方式運行war包
(1) pom.xml打包的方式仍然未war包，將對應的jsp和servlet的包依賴改為compile(默認就是)即可。繼成SpringBootServletInitializer，與上面一樣。這里打包方式仍然是war包的原因是如果打的是jar包不會打WEB-INF目錄，也就是沒有jsp頁面，所以導致訪問報錯。
(2)pom.xml將jsp與servlet與tomcat的包依賴改為默認的compile

(3)執行clean package打包即可

(5)解壓war包查看目錄:(與上面的目錄一樣，只是沒有provided的jar包所以沒有對應的目錄)
也就是發布到獨立的tomcat與獨立運行war包的區別就是是否將JSP以及tomcat依賴的jar包打包出來，如果打的包里面有tomcat以及jsp相關包就可以獨立運行war包，否則依賴tomcat容器。
