SpringBoot 1.4升级中遇到的奇葩问题

截止写这片内容时，springboot的最新版本是1.4 ，现在项目中使用的springboot版本是1.3.5，jdk环境是1.7。在升级springboot从1.3.5升级到1.4的时候出现了一些小问题，这里记录下来。

log4j变成log4j2

在我使用的1.3.5版本的boot的使用的是log4j，在boot1.4的版本中，就需要使用log4j2，否则会出现如下错误，

解决方法如下，更改依赖：

<dependency>
    <groupId>org.springframework.bootgroupId>
    <artifactId>spring-boot-starter-log4j2artifactId>
dependency>

jetty的支持

在1.3.5的时候使用jetty的时候在pom中直接依赖，如下：

<dependency>
    <groupId>org.springframework.bootgroupId>
    <artifactId>spring-boot-starter-jettyartifactId>
<dependency>

但是在1.4.0中，这个貌似不行了，会出现下面错误：

看意思应该是少了bean，经查询发现，需要自己手动的配置bean factory，如下：

package com.test;

import org.springframework.boot.context.embedded.jetty.JettyEmbeddedServletContainerFactory;
import org.springframework.context.annotation.Bean;
import org.springframework.context.annotation.Configuration;

@Configuration
public class MyConfig {

    public @Bean JettyEmbeddedServletContainerFactory servletContainer() {
        JettyEmbeddedServletContainerFactory factory = new JettyEmbeddedServletContainerFactory();
        return factory;
    }
}

不知道为什么需要这样做，以前的不是挺好的吗，如果你想到其他的方法可以联系我邮箱：[email protected]。

这很明显，就是jdk版本不符合，初步排查因为springboot 1.4默认引用的jetty版本是9.3的，同时jetty9.3依赖jdk8，因此才会出现上面问题。下面是官方的版本定义：

解决方法：

如果可以升级jdk就可以彻底解决上面问题；如果不能升级jdk则可以使用下面方法：
1. 在properties标签中中增加jetty的版本号引用。

<properties>
    <project.build.sourceEncoding>UTF-8project.build.sourceEncoding>
    <jetty.version>8.1.15.v20140411jetty.version>
    <jetty-jsp.version>2.2.0.v201112011158jetty-jsp.version>
properties>

1. 在dependency中排除掉‘org.eclipse.jetty.websocket’的所有引用

<dependency>
    <groupId>org.springframework.bootgroupId>
    <artifactId>spring-boot-starter-jettyartifactId>
    <exclusions>
        <exclusion>
            <groupId>org.eclipse.jetty.websocketgroupId>
            <artifactId>*artifactId>
        exclusion>
    exclusions>
dependency>

ok，到此位置，启动解决问题。启动测试，如下：

testing的改变

在开发的时候我们经常需要进行单元测试，如果是开发web项目的时候还需要对http接口进行测试，在springboot1.3.5版本的时候我们只需要在test class上配置如下

package ess.api;

import org.junit.Test;
import org.junit.runner.RunWith;
import org.springframework.boot.test.SpringApplicationConfiguration;
import org.springframework.boot.test.WebIntegrationTest;
import org.springframework.test.context.junit4.SpringJUnit4ClassRunner;

import ess.Startup;

@RunWith(SpringJUnit4ClassRunner.class)
@SpringApplicationConfiguration(classes = Startup.class)
@WebIntegrationTest
public class MyTest2 {
    @Test
    public void test() {

    }

}

但是这个代码升级到了1.4.1版本的时候出现了deprecated，就是说这种注解配置过时了，可能会在未来的某个版本取消掉，因此可以改成如下

package ess.api;

import org.junit.Test;
import org.junit.runner.RunWith;
import org.springframework.boot.test.context.SpringBootTest;
import org.springframework.boot.test.context.SpringBootTest.WebEnvironment;
import org.springframework.test.context.junit4.SpringRunner;

import ess.Startup;

@RunWith(SpringRunner.class)
@SpringBootTest(classes=Startup.class,webEnvironment = WebEnvironment.DEFINED_PORT)
public class MyTest2 {
    @Test
    public void test() {

    }

}

这样就ok了，更多可以参考 http://docs.spring.io/spring-boot/docs/1.4.1.RELEASE/reference/htmlsingle/#boot-features-testing 官方文档。
