Question

我正在开发一个使用 spring boot 和maven的网络项目。我能够成功地在 JAVA 1.8 上运行我的应用程序但是当我尝试运行它时 JAVA 1.6 我正面临问题。

我的 POM.XML

我尝试过很多网站，但无法解决任何人都可以帮助我使用支持java 1.6的弹簧启动的pom.xml吗？

Answer 1

默认情况下，Spring Boot 1.4.4.RELEASE需要Java 7和Spring Framework 4.3.6.RELEASE或更高版本。您可以使用带有Java 6的Spring Boot和一些其他配置。有关更多详细信息，请参见第81.11节“How to use Java 6”。为Maven（3.2+）和Gradle（1.12或2.x）提供显式构建支持。不推荐支持Gradle 2.8及更早版本。不支持Gradle 3。

以上回答是帮助，但我想添加我在pom.xml中进行的详细更改以解决我的问题。

我们只需要从依赖项中排除jackson jar，在属性中我们必须将java版本设置为1.6。

请参阅我的pom.xml以在java 1.6中运行spring boot。

   <properties>
        <!-- <servlet-api.version>3.0</servlet-api.version> -->
        <java.version>1.6</java.version>
        <tomcat.version>7.0.59</tomcat.version>
    </properties>

<dependency>
            <groupId>org.springframework.boot</groupId>
            <artifactId>spring-boot-starter-web</artifactId>
            <exclusions>
                <exclusion>
                    <artifactId>jackson-databind</artifactId>
                    <groupId>com.fasterxml.jackson.core</groupId>
                </exclusion>
                <exclusion>
                    <artifactId>jackson-annotations</artifactId>
                    <groupId>com.fasterxml.jackson.core</groupId>
                </exclusion>
                <exclusion>
                    <artifactId>jackson-core</artifactId>
                    <groupId>com.fasterxml.jackson.core</groupId>
                </exclusion>            
            </exclusions>
        </dependency>

<!-- need to add jackson 2.6 jars -->
       <dependency>
            <groupId>com.fasterxml.jackson.core</groupId>
            <artifactId>jackson-databind</artifactId>
            <version>2.6.0</version>
        </dependency>

        <dependency>
            <groupId>com.fasterxml.jackson.core</groupId>
            <artifactId>jackson-annotations</artifactId>
            <version>2.6.0</version>
        </dependency>

        <dependency>
            <groupId>com.fasterxml.jackson.core</groupId>
            <artifactId>jackson-core</artifactId>
            <version>2.6.0</version>
        </dependency>
