springboot整合JSP以及发布项目到独立的tomcat中与打成jar包使用

　　之前研究了springboot整合freemarker与thymeleaf的使用。也研究了springboot发布到独立的tomcat的使用以及使用自带的tomcat打成jar包的使用，下面研究集成JSP之后的使用。

　　建议还是使用官方提倡的thymeleaf模板。而且thymeleaf与html很好的集成，便于前后端人员开发。

1.集成JSP

pom.xml添加JSP相关依赖:

复制代码
        <!-- 使用jsp引擎，springboot内置tomcat没有此依赖 -->
        <dependency>
            <groupId>org.apache.tomcat.embed</groupId>
            <artifactId>tomcat-embed-jasper</artifactId>
            <scope>provided</scope>
        </dependency>
        <!-- 添加servlet依赖模块 -->
        <dependency>
            <groupId>javax.servlet</groupId>
            <artifactId>javax.servlet-api</artifactId>
            <scope>provided</scope>
        </dependency>
        <!-- 添加jstl标签库依赖模块 -->
        <dependency>
            <groupId>javax.servlet</groupId>
            <artifactId>jstl</artifactId>
        </dependency>
复制代码

 

application.properties文件中配置相关信息:

############################################################
#
# JSP 配置
#
############################################################
spring.mvc.view.suffix=.jsp
spring.mvc.view.prefix=/WEB-INF/jsp/

注意:如果项目中集成了thymeleaf，需要关掉thymeleaf，否则会将jsp作为thymleaf解析，如下:

# 关闭缓存, 即时刷新
spring.thymeleaf.cache=false
#关闭thymeleaf引擎
spring.thymeleaf.enabled=false

 

对应的目录结构:

 

后台Controller测试:

复制代码
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";
    }
}
复制代码

访问测试:

 

2.测试项目发布到独立的tomcat运行

 如果发布到独立的tomcat运行的话，与之前的的一样

(1)继承SpringBootServletInitializer，重写configure方法。

复制代码
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;

// 发布到独立的Tomcat需要继承SpringBootServletInitializer类并重写configure方法

@Configuration // 通过该注解来表明该类是一个Spring的配置，相当于一个xml文件
@ComponentScan(basePackages = "cn.qlq") // 配置扫描包
public class SpringConfig extends SpringBootServletInitializer {
    @Override
    protected SpringApplicationBuilder configure(SpringApplicationBuilder builder) {
        // 设置启动类，用于独立tomcat运行的入口
        return builder.sources(SpringConfig.class);
    }

}
复制代码

 

 (2)pom.xml打包的方式改为war包，将对应的jsp和servlet的包依赖改为provided即可。

 (3)执行clean package打包即可

(4)将打的war包拷贝到tomcat的webapps目录下运行即可

(5)查看tomcat启动解压后的目录结构:(与之前研究的一样，加了springboot的东西,而且provided依赖的jar包也会打到一个目录中)

 

 

 

 

3.打成war包运行并以java -jar的方式运行war包

(1) pom.xml打包的方式仍然未war包，将对应的jsp和servlet的包依赖改为compile(默认就是)即可。继成SpringBootServletInitializer，与上面一样。这里打包方式仍然是war包的原因是如果打的是jar包不会打WEB-INF目录，也就是没有jsp页面，所以导致访问报错。

(2)pom.xml将jsp与servlet与tomcat的包依赖改为默认的compile

 (5)解压war包查看目录:(与上面的目录一样，只是没有provided的jar包所以没有对应的目录)

 

 

 　　也就是发布到独立的tomcat与独立运行war包的区别就是是否将JSP以及tomcat依赖的jar包打包出来，如果打的包里面有tomcat以及jsp相关包就可以独立运行war包，否则依赖tomcat容器。
