我正在使用 Gradle.这是我的 build.gradle 文件:
Iam using Gradle.This is my build.gradle file:
buildscript {
ext {
springBootVersion = '1.3.1.RELEASE'
}
repositories {
mavenCentral()
}
dependencies {
classpath("org.springframework.boot:spring-boot-gradle-plugin:${springBootVersion}")
}
}
apply plugin: 'java'
apply plugin: 'eclipse'
apply plugin: 'idea'
apply plugin: 'spring-boot'
apply plugin: 'war'
war {
baseName = 'Example-Application'
version = '0.0.1-SNAPSHOT'
}
sourceCompatibility = 1.8
targetCompatibility = 1.8
repositories {
mavenCentral()
}
dependencies {
compile('org.springframework.boot:spring-boot-starter-data-jpa')
compile('org.springframework.boot:spring-boot-starter-security')
compile('org.springframework.boot:spring-boot-starter-web')
compile('org.apache.tomcat.embed:tomcat-embed-jasper:8.0.30')
compile('javax.servlet:servlet-api:2.5')
compile('javax.servlet:jstl:1.2')
runtime('mysql:mysql-connector-java')
providedRuntime 'org.springframework.boot:spring-boot-starter-tomcat'

}
eclipse {
classpath {
containers.remove('org.eclipse.jdt.launching.JRE_CONTAINER')
containers 'org.eclipse.jdt.launching.JRE_CONTAINER/org.eclipse.jdt.internal.debug.ui.launcher.StandardVMType/JavaSE-1.8'
}
}
task wrapper(type: Wrapper) {
gradleVersion = '2.9'
}
这是配置类:
package com.example.he.config;
import org.springframework.context.annotation.Configuration;
import org.springframework.web.servlet.config.annotation.ViewControllerRegistry;
import org.springframework.web.servlet.config.annotation.WebMvcConfigurerAdapter;
@Configuration
public class MvcConfig extends WebMvcConfigurerAdapter {
@Override
public void addViewControllers(ViewControllerRegistry registry) {
registry.addViewController("/city").setViewName("city");
registry.addViewController("/").setViewName("city");
registry.addViewController("/userAdd").setViewName("user");
registry.addViewController("/created").setViewName("created");
registry.addViewController("/createblog").setViewName("blog");
registry.addViewController("/login").setViewName("login");
registry.addViewController("/home").setViewName("home");
}
}
这是我的应用程序类:
package com.example.he;
import org.springframework.boot.SpringApplication;
import org.springframework.boot.autoconfigure.EnableAutoConfiguration;
import org.springframework.boot.autoconfigure.SpringBootApplication;
import org.springframework.boot.builder.SpringApplicationBuilder;
import org.springframework.boot.context.web.SpringBootServletInitializer;
import org.springframework.context.annotation.ComponentScan;
import org.springframework.context.annotation.Configuration;
import org.springframework.scheduling.annotation.EnableScheduling;
@SpringBootApplication
public class ExampleApplication extends SpringBootServletInitializer{
public static void main(String[] args) throws Exception {
SpringApplication.run(ExampleApplication.class, args);
}
@Override
protected SpringApplicationBuilder configure(SpringApplicationBuilder application) {
return application.sources(ExampleApplication.class);
}
}
我也尝试过这些注释.
@ComponentScan
@EnableAutoConfiguration
@Configuration
我是 spring 新手，我不太了解这些注释的作用.我尝试关注其中的一些，但无法解决问题.
I am new to spring and i don't really understand what these annotations do.I tried following some of these but couldn't fix the issue.
Spring Boot:无法启动 EmbeddedWebApplicationContext 由于缺少 EmbeddedServletContainerFactory bean
Spring Boot 测试:由于无法启动 EmbeddedWebApplicationContext缺少 EmbeddedServletContainerFactory bean
我尝试使用控制台(gradle build)构建应用程序，构建成功，但运行 war 给我一个错误:Unable to start embedded Tomcat.有人可以帮我吗?
I tried building the application using console(gradle build), build is successful but running the war gives me an error: Unable to start embedded Tomcat . Could someone please help me ?
推荐答案
我能够让您的应用程序启动并运行.我为让它运行所做的唯一更改是在你的 build.gradle 文件中注释掉你的几个依赖项.
I was able to get your application up and running. The only change I made to get it running was to comment out a couple of your dependencies in your build.gradle file.
在下面的依赖块中，注释掉了 3 行.我注释掉的 spring-boot-start-jpa 行只是因为我没有配置的数据源.
In the dependencies block below, 3 lines are commented out. The spring-boot-start-jpa line I commented out only because I did not have a configured dataSource.
但是，如果您只注释掉 servlet-api 和 jstl 依赖项，您的应用应该可以毫无问题地启动，这对我来说确实如此.
However, if you only comment out the servlet-api and jstl dependencies, your app should start without issue, it did for me.
dependencies {
//compile('org.springframework.boot:spring-boot-starter-data-jpa')
compile('org.springframework.boot:spring-boot-starter-security')
compile('org.springframework.boot:spring-boot-starter-web')
compile('org.apache.tomcat.embed:tomcat-embed-jasper:8.0.30')
//compile('javax.servlet:servlet-api:2.5')
//compile('javax.servlet:jstl:1.2')
runtime('mysql:mysql-connector-java')
providedRuntime 'org.springframework.boot:spring-boot-starter-tomcat'
testCompile('org.springframework.boot:spring-boot-starter-test')
}
