springboot jsp jar 部署支持指定 jsp 位置

1. spring boot 支持 jsp

pom:

<dependency>
    <groupId>org.springframework.boot</groupId>
    <artifactId>spring-boot-starter-web</artifactId>
</dependency>
<dependency>
    <groupId>javax.servlet</groupId>
    <artifactId>jstl</artifactId>
</dependency>
<dependency>
    <groupId>org.apache.tomcat.embed</groupId>
    <artifactId>tomcat-embed-jasper</artifactId>
</dependency>
<dependency>
    <groupId>javax.servlet</groupId>
    <artifactId>javax.servlet-api</artifactId>
</dependency>

2. 启动类添加 InternalResourceViewResolver bean 以便 controller 返回 jsp 可以获取到

//java项目 www.1b23.com
@Bean
public InternalResourceViewResolver setupViewResolver() {
    InternalResourceViewResolver resolver = new InternalResourceViewResolver();
    resolver.setPrefix("/");
    resolver.setSuffix(".jsp");
    return resolver;
}

3. 启动类添加 ConfigurableServletWebServerFactory bean 以便可以获取到 jsp 文件

//java项目 www.1b23.com
@Bean
public ConfigurableServletWebServerFactory serverFactory() {
    ConfigurableServletWebServerFactory aFactory = new TomcatServletWebServerFactory();
    aFactory.setDocumentRoot(new File("jsp 服务器全路径"));
    return aFactory;
}

 本地开发时 serverFactory() 方法可直接返回 new TomcatServletWebServerFactory()
